James George Tomkins, known professionally as Big Jim Sullivan, was an English musician whose career started in 1958. He was best known as a session guitarist. In the 1960s and 1970s he was one of the most in-demand studio musicians in the UK and performed on around 750 charting singles over his career, including 54 UK Number One hits. Sullivan became one of the most sought-after guitarists throughout the 1960s and the 1970s, in part because of his flexibility in playing different styles of music. He was often referred to as "Big Jim" both for his physical appearance and as he was usually first choice to play guitar on sessions for major musicians and bands. Another session musician at the time, and at some of the same sessions, Jimmy Page, was referred to as "Little Jim." In 1974, Sullivan teamed up with the record producer, Derek Lawrence, to form the record label, Retreat Records. One album release was Big Jim's Back. He fronted a band called Tiger, alongside vocalist Nicky Moore, releasing three albums under this name before the group split up in 1976. This is the third of those records.
