During his backstage theatre job, Sellers began practising on a set of drums that belonged to the band Joe Daniels and his Hot Shots. Daniels noticed his efforts and gave him practical instructions. The instrument greatly suited Sellers's temperament and artistic skills. Spike Milligan later noted that Sellers was very proficient on the drums and might have remained a jazz drummer, had he lacked his skills in mimicry and improvisation. As the war progressed, Sellers continued to develop his drumming skills, and played with a series of touring bands, including those of Oscar Rabin, Henry Hall and Waldini, as well as his father's quartet, before he left and joined a band from Blackpool. Sellers became a member of the Entertainments National Service Association (ENSA), which provided entertainment for British forces and factory workers during the war. Sellers also performed comedy routines at these concerts, including impersonations of George Formby, with Sellers accompanying his own singing on ukulele.
