What year did Hugh Laurie compose the song mystery.?

We're doing a 50s-60s music themed dance thing at school and a friend of mine decided to do mystery by Hugh Laurie, but the teacher says that it needs to be from 50s-60s and he says it is, so i wanted to know, and i mean the original from Bit of Fry and Laurie, not the new one he just redid.
