Humphrey Lyttelton's eight-piece band featured, aside from himself on the trumpet and clarinet: Ray Wordsworth  on the trombone; Jimmy Hastings on the alto sax, clarinet and flute; Jo Fooks on the tenor saxophone and flute; Rob Fowler on the tenor sax, baritone sax and clarinet; Ted Beament on the piano; John Rees-Jones on the double bass and Adrian Macintosh on the drums.The band maintained a busy schedule, frequently performing sold-out shows across the country. Performances occasionally included a guest singer, or a collaboration with another band. During the 1990s the band toured with Helen Shapiro in a series of Humph and Helen concerts. They also featured in several Giants of British Jazz tours with Acker Bilk and George Melly and John Chilton's Feetwarmers.Lyttelton had a long established professional relationship with UK singer Elkie Brooks. After working together in the early 1960s they rekindled their working partnership in early 2000 with a series of sold out and well received concert performances. They released the critically acclaimed album Trouble in Mind in 2003 and continued to perform occasional concerts in support of this work.
