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 gigged regularly in the city and were signed after a performance 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 "Somebody Help Me", the group's first number one single. In 1966 they followed this with "When I Come Home" and "Keep On Running". For the German market the group released "Det war in Schöneberg, im Monat Mai"/"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 beginning of 1967 the group released two more massive hits: "Gimme Some Lovin'" (which was re-released in a live, nine minute long version by Traffic in 1971); and "I'm A Man" (January 1967). These tracks proved to be their two most well-known successes, especially in their biggest market, the U.S.
Behind the scenes, their record company tried to put together a supergroup around the talents of the very young Steve Winwood. Steve (vocals), and his brother Muff Winwood (bass guitar) both left, with Steve forming Traffic. In a so-called joint venture, the movie soundtrack to the film Here We Go Round the Mulberry Bush featured both bands.
Traffic took off in May 1967 with "Paper Sun". Despite the Winwoods' departure, Spencer Davis continued on and released more singles, but they were only minor hits, such as "Time Seller" in July 1967, although the B-side, called "Don't Want You No More" was given some airplay
