"Lady" is a popular song written and performed by the rock band Styx. It was first released on Styx II in September 1972 and was a local hit in the band's native Chicago, but failed to chart nationally. The song gained success when Styx left Wooden Nickel Records to move to A&M Records, and the song was re-released in 1974, peaking at #6. It was written by Dennis DeYoung for his wife.
