How old was Steve Winwood when he wrote the song 'I'm a Man'?

Steve Winwood (1948) was 18 years old when the song was written and released.. It was first recorded in 1967 by the Spencer Davis Group. Winwood sang lead vocals and played keyboards. The song was a hit in the United Kingdom and the United States, reaching No. 9 and No. 10, respectively. It has been recorded by many other groups over the years, most successfully by Chicago Transit Authority, whose version charted at No. 8 in the UK in 1970 and No. 49 in the US in 1971.

In 1967, Steve left the Spencer Davis Group and co-founded Traffic. Beloved for their eclectic style and superbly crafted songs, Traffic routinely defied convention to celebrate a host of diverse sounds and influences. Landmark albums such as ‘Mr. Fantasy’, ‘The Low Spark Of High Heeled Boys’, and ‘John Barleycorn Must Die’ confirmed their position as one of the most important British groups of the 1960’s and 1970’s.

Eager to try his hand with other creative partnerships, Winwood left Traffic in 1969 to form a new group called Blind Faith with Eric Clapton and Ginger Baker. The pairing of Winwood with Cream’s Eric Clapton, Ginger Baker and later, bassist Rick Grech, created what many critics dubbed Rock’s first super group. The international popularity of ‘Blind Faith’, the group’s sole #1 album, confirmed their special chemistry. Blind Faith staples written by Winwood such as “Can’t Find My Way Home” and “Had To Cry Today” continue to rank among his finest achievements.
