Michael Copley and David Adam Gillespie (Dag) Ingram met when they were students at Cambridge University.
According to the liner notes of their first recording, their musical association began when they found themselves at Blackfriars station without enough money for the fare to get home.
In an attempt to raise the money from passers-by, they played The Entertainer and Eine kleine Nachtmusik for a while, until they were asked to leave by a London Transport official.
Ian Moore played piano accordion, used his voice, and occasionally other percussion instruments or props.
Copley played a variety of woodwind instruments, including flute, recorder, ocarina, and crumhorn.
