Another report of the same meeting states:

“the gentleman who had spoken from the window made his appearance with a mouth-organ. (vulgo° a pandean piper) stuck beneath his chin, and a middling sized drum, covered with a piece of old green baize, hung horizontally across his stomach.”

In 1820 at the Peale Museum in Philadelphia, USA, when 'Signor Helene and his Pandean Band' performed he did play on his 5 different instruments at the same time. These included the Italian viola, Pandean pipes, Chinese bells, Turkish cymbals, and tenor drum; during performances he also imitated a mockingbird and a canary with his voice.

1822 Newspaper report:

"Yesterday a company of blind itinerant Musicians, consisting of a clarionet, two violins, and bass viol, were performing in Albemarle Street, Piccadilly, some of the choicest pieces of modern music, in a style which drew together a very numerous audience. In the midst of this delightful harmony an evil genius suddenly appeared in the person of another member of the profession ; who, jealous of the applause his brethren bad obtained, or envious of the harvest they were reaping from their exertions, exerted himself so successfully with a drum and pandean pipes as to stifle in the birth the soul-enlivening notes from the silver toned cremonas. The little band for a short time endured the discord the vile pandean occasioned with the most philosophic forbearance; but finding all their endeavours to be heard completely ineffectual were compelled to desist ,expecting their opponent would immediately discontinue his annoyance. But in this they were disappointed ; the fellow still kept up the most astounding noise with his drum, to the infinite amusement of the bystanders and chagrin of the little band who manifested their displeasure in rather uncourtly terms. Still the provoking pandean was not to be silenced. He continued blowing and thumping, till he was black in the face, without once deigning to notice his enraged brethren. The little band apparently unwilling to yield, and puzzled how to proceed, held a council of war, in which it was resolved to ascertain, who could play longest. The clarionet immediately struck hp, followed by the violins and grumbling bass viol. The full blown cheeks of the former presented an amusing contrast with the lank visage of the Pandean, and the contest was for some time severe and doubtful. The latter, however, who from the commencement had allowed himself but little or no breathing time, began to exhibit evident symptoms of 'exhaustion and ultimately was compelled to cease. The triumph of the little party was, however, but of short duration foe the fellow who appeared to recollect that though short of breath, he had not lost the use of his arms, commenced a solo on the drum which he belaboured so unmercifully as to compel the luckless fiddlers to put up their fiddle-sticks in despair.. A short pause ensued, which was but the prelude to a storm. — The little party, enraged beyond measure at the opposition they had experienced sent forth a volley of abuse which quite overwhelmed their opponent. Four to one, he observed, with the most provoking sang froid, was a fearful odds, and again had recourse to his drum, with which he kept up such a clatter, as completely silenced, and ultimately drove his antagonists from the field.  We understand the poor fiddlers, in the course of their peregrinations, had entered the street in question, and had been pretty successful in drawing the loose pence from the pockets of their hearers. The Pandean, who had for some time enjoyed the exclusive right of playing in this street, viewed this unconscious invasion of the blind men as a direct attack on his privilege, and formed the resolution on which he ultimately succeeded to drum ',em out."

Puppet Booths

Some London street entertainers earned their living playing in the streets in conjunction with puppet booths or Punch and Judy shows. Henry Mayhew interviewed many street entertainers including a 'street musicianer', a performer on 'drum and pipes', who recounted what he did some 30 years before. "I have played the pandean pipes and the drum for thirty years to street exhibitions of all kinds. I married a young woman that I fell in love with, in the music line. She played a hurdy-gurdy in the streets, so I bought pandean pipes, as I was always fond of practising music, and I joined her. Times for street-musicianers were good then, but I was foolish. I 'm aware of that now; but I wasn't particularly partial to hard work; besides, I could make more as a street-musicianer. When I first started, my wife and I joined a fantoccini. [puppet theatre] It did well. My wife and I made from 9s. to 10s. a-day. source

1824 Greenwich ParkSussex & Surrey Chronicle - Wednesday 16 June 1824

A street puppet theatre came along the road in 1825:

"Its coming was announced by a man playing the Pan-pipes, or "mouth-organ," which he accompanied by beating the long drum;
after him followed the theatre, consisting of a square frame-work about ten feet high, ...
The band of two instruments was set in motion by its performer, who took his station on one side, and the carrier of the theatre assuming the important office of money collector....
Boys came running in from the fields, women with children got "good places," windows were thrown up and well filled, the drummer beat and blew away lustily, the audience increased every minute, .......
In about a minute the tune altered, and the show began".

This description is accompanied by a drawing of a puppet booth.

Henry Mayhew (1812 - 1887)was a social researcher, journalist, playwright and advocate of reform published 'London Labour and the London Poor' in 1851. This was a groundbreaking and influential survey of the poor of London.

A painting entitled 'Sweeps Day in Upper Lisson Street, Paddington' painted in the late 1830's shows a 'Jack-in-the-Green' with other historically-based characters dancing to the pan-pipes and tabor in the street. (Museum of London Collection). So there is the possibility that the piper 'who also played the drum' as remembered by an elderly gentleman in 1860 recalling a "Jack in Green" procession of his childhood may have played the panpipes too. source
