"Cannonball" is the opening track from Supertramp's 1985 album Brother Where You Bound. It was written and sung by keyboardist Rick Davies entirely in the chord of G minor. Davies stated in an interview "I did it simply to see if it could be done". The lyrics to the song may have been seen as a veiled message to former member Roger Hodgson but Davies revealed in a French radio interview that they were inspired by a less than perfect concert promoter whom he refused to name. On the flip side of the 12-inch release is a 10-minute instrumental version of the song.
