Q: Passage: The song "Year of the Cat" began as "Foot of the Stage", a song written by Stewart in 1966 after seeing a performance by comedian Tony Hancock whose patter about "being a complete loser" who might as well "end it all right here" drew laughs from the audience: Stewart's intuitive response that Hancock was in genuine despair led to the writing of "Foot of the Stage". It was the melody for this never-recorded song which Stewart set the lyrics of "Year of the Cat" to in 1975: pianist Peter Wood was given a co-writing credit on the song in recognition of his piano riff on the recorded track.
