The Spencer Davis Group was a mid 1960s British beat group from Birmingham, England, founded by Spencer Davis (born 17 July 1939, Swansea, Wales).
Spencer Davis moved to Birmingham from London in 1960 to study. In 1963 he recruited the Winwood brothers and started the Spencer Davis Group. The band performed regularly in the city and were signed after an appearance in a local club.
The group's first professional recording was a cover version of "Dimples", but they came to success at the end of 1965 with "Keep On Running", the group's first number one single. In 1966 they followed this with "Somebody Help Me" and "When I Come Home". For the German market the group released "Det war in Schöneberg, im Monat Mai" and "Mädel ruck ruck ruck an meine grüne Seite" (the first is from a 1913 Berlin operetta, the second is a Swabian traditional) as a tribute single for that audience, because Spencer Davis had studied in West Berlin in the early 1960s. By the end of 1966 and the beginning of 1967, the group released two more hits: "Gimme Some Lovin'" (which was re-released in a live, nine-minute version by Traffic in 1971); and "I'm a Man" (January 1967). These tracks proved to be their two best-known successes, especially in their biggest market, the U.S.
