Russell's jazz career began at the age of 15, when he played as a New Orleans-style trombonist with the London-based Washington and Lee Swing, George Webb's Dixilanders
George Webb. In 1946 he formed the pioneering trad band, the Russell-Wickham Hot Six, which he led with the trumpeter Alan Wickham. At this time he was known as Rag's Russell because he played a little ragtime on the piano. In the fledgling years of his career, he also performed vocals. He played with
Vic Lewis,
Oscar Rabin,
Ralph Sharon,
Jack Parnell and
Tony Crombie. In 1957 he led a band of his own, after which, he began his association with
Johnny Dankworth, first as a trombonist in his big band. Here he had the opportunity to both arrange and compose - a favourite jazz piece often included in performances was Russell's "Joe And Lol's Blues". He recorded quite extensively with the band from December 1956 and can be heard on most of the bands
Parlophone,
Columbia,
Top Rank and
Fontana albums. He was the band's road manager for many years. In 1959 he went with the band to play at the
Newport Jazz Festival. Russell studied composition with
Richard Rodney Bennett and
Bill Russo. He was in Russo's London Jazz Orchestra and took over running this when Russo returned to the United States in 1965. In his later years, Russell became busier as a composer and won acclaim in 1966 for writing the score for the musical
Matchgirls, which has enjoyed longevity into the 21st century. In this same year, with Johnny Dankworth and Johnny Flanagan, he formed Music Activity Management Ltd. Russell continued to play in the band and on sessions for other leaders. He also wrote music for shows and TV series such as
On the Buses, and the children's programme
The Herbs. Russell suffered for many years with
Hodgkin's disease. During his final illness, he was commissioned to compose a Mass, a Missa Brevis, which was completed shortly before he died. In his final composition, he moves from an overt jazz idiom, to encompass classical features of vocal scoring and instrumentation. "The Russell Mass" stands somewhere between the jazz, classical and popular styles of the 20th century. Russell appeared in
