The Spencer Davis Group was a mid-1960s British beat group from Birmingham, England formed by Spencer Davis with Steve Winwood and his brother Muff Winwood. Their three best known songs are "Keep on Running", a number one in the UK Singles Chart written by reggae musician Jackie Edwards; and "Gimme Some Lovin'" and "I'm a Man". Steve Winwood left in 1967, to form Traffic before joining Blind Faith, then forging a career as a soloist. After releasing a few more singles the band ceased activity in 1968. Davis started a new group in 2006, although only he remains from the 1960s line-ups.
