It was while playing in the Chris Barber Jazz Band in 1954 that Donegan recorded a cover of Leadbelly's "Rock Island Line
" to the accompaniment of a passing girl playing the washboard. The song was a big hit and launched the skiffle music craze, a kind of jazz/folk/country/blues fusion usually using homemade or improvised instruments. The homemade music inspired many Britons to take up the guitar, including a young John Lennon. (His first band, The Quarrymen, was a skiffle group).
