 The Blockheads' sound drew from its members' diverse musical influences, which included jazz, rock and roll, funk, and reggae, and Dury's love of music hall.Jankel left the band temporarily and relocated to the U.S. after the release of "What A Waste" (his organ part on that single was overdubbed later) but he subsequently returned to the UK and began touring sporadically with the Blockheads, eventually returning to the group full-time for the recording of "Hit Me With Your Rhythm Stick"; according to Mick Gallagher, the band recorded 28 takes of the song but eventually settled on the second take for the single release.Partly due to personality clashes with Dury, Jankel quit the group again in 1980, after the recording of the "Do It Yourself" LP, and he returned to the U.S. to concentrate on his solo career.
