In 1948 Mudele became a founder member of Club Eleven, a Soho nightclub open between 1948 and 1950 which played a significant role in the emergence of the
bebop jazz movement in Britain. The club was so named because it was a musicians cooperative with 11 founders – business manager Harry Morris along with ten British bebop players, including Mudele: the others were
Lennie Bush,
Leon Calvert,
Tony Crombie, Bernie Fenton (1921-2001, piano), Laurie Morgan (1926-2020, drums), Johnny Rogers (1926-2016, saxophone),
Tommy Pollard (1923-1960, piano and vibes),
Ronnie Scott, and
Hank Shaw. John Dankworth was also involved, heading up one of two house bands with Mudele on bass. After the club was closed Mudele became a founder member of the John Dankworth Seven, while also continuing to play with others, including
Ambrose, Jack Nathan, the Norman Burns Quintet and
Kenny Baker's Quartet. He formed his own band, Blue Room, for a year (1952-3, including the Jamaican saxophonist
Joe Harriott), was a member of the house band of the Coconut Grove nightclub in
Regent Street, then stayed for an extended period with the
Tommy Whittle Quintet (from 1954) and later the
Tony Kinsey Quartet. During this period Mudele also played for
Sophie Tucker,
Judy Garland and
Billy Eckstine and recorded with (among others)
Larry Adler,
Humphrey Lyttelton, the Melody Maker All Stars,
George Chisholm and
Sid Phillips. ==Session musician==
