[video description: two women playing a violin and a banjo. where ordinarily each instrument is a two-handed single-player operation, one hand working the strings on the neck of the instrument and the other plucking the strings on the banjo body or bowing the strings on the violin body, here both instruments are two-player because each woman is working the neck of one instrument and the body of another. partway through, a third woman comes up with a tin whistle, which again is ordinarily single-player, requiring both hands on the holes and mouth blowing into the mouthpiece; here, the third woman does the hands part for the whistle while one of the first two does the blowing.]
