"I'm a Man" is a song written by Steve Winwood and record producer Jimmy Miller. 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 performers over the years, most successfully by Chicago, whose version charted at No. 8 in the UK in 1970 and No. 49 in the US in 1971.

Original song

The original recording was a Hammond organ-driven blues rock track released as a single by the Spencer Davis Group in early 1967, reaching No. 9 in the UK Singles Chart. In the US, it peaked at No. 10 in the US Billboard Hot 100, as well as No. 48 in the magazine's Top Selling R&B Singles. It was the last hit single by the band before the brothers Steve and Muff Winwood left to pursue their own separate careers. The song is included on the band's 1967 album, I'm a Man.

Chicago version

Chicago (then known as Chicago Transit Authority) recorded a cover version of "I'm a Man" for their 1969 debut album, The Chicago Transit Authority. When the band's popularity surged after their second album, "I'm a Man" was released as the B-side to a re-release of "Questions 67 and 68". Radio stations ended up playing both sides, and "I'm a Man" reached No. 49 on the US Billboard Hot 100 chart in 1971. In the UK, it reached No. 8 and No. 13 in Ireland. Chicago personnel:
