Martin produced comedy and novelty records in the early 1950s, working with Peter Sellers, Spike Milligan, and Bernard Cribbins, among others. His career spanned more than six decades of work in music, film, television and live performance. He held a number of senior executive roles at media companies and contributed to a wide range of charitable causes, including his work for The Prince's Trust and the Caribbean island of Montserrat.
