Dr. Feelgood are a British pub rock band formed in 1971. Hailing from Canvey Island, Essex, they are best known for early singles like "Back in the Night" and "Roxette". The group's original distinctively British R&B sound was centred on Wilko Johnson's choppy guitar style. Along with Johnson, the original band line-up included singer Lee Brilleaux and the rhythm section of John B. Sparks, known as "Sparko", on bass guitar and John Martin, known as "The Big Figure", on drums. Although their most commercially productive years were the early to mid-1970s, they continue to tour and record to this day.
