Previously a german language teacher, he was born Spencer Davies and was part of a group. The manager decided to make him the leading light, dropped the 'e' and hence the name of the group. Stevie Winwood was the other leading light and much if not almost all of the composing. Keep on runnin' was their greatest hit and displaced the Beatles in 1964 from the top of the chart. Often used as THE track from that year by broadcasters. Many other tracks followed, I'm a Man being one of the very best.
