For many years he wrote books and 49 had been published by the end of 2022. More than half of these were crime fiction; the non-fiction books were mainly on cinema and jazz. Long ago there were a few television plays and a stage play. For a number of years he worked with Colin Larkin on his Encyclopedia of Popular Music and the BTOE, contributing 5-6000 entries to these projects. His first Jazz Journal article was in the mid-1970s, record reviews beginning a decade later. His jazz books include a biography of Gene Krupa and three books in collaboration with Mike Pinfold: The Jazz Singers, The Big Band Years and Singing Jazz. Other than jazz, he enjoyed the blues, opera, old country, gospel, R&B, and popular songs of the 1930s and 40s. Bruce Crowther died in August 2023 as reported here.
