The UK and US single releases were different versions from the same recording sessions. The take that EMI, the Animals' parent record company, sent to MGM Records, the group's American label, was mistakenly one that had not been selected for release elsewhere. The two versions are most easily differentiated by the lyric at the beginning of the second verse: in the US version the lyric is, "See my daddy in bed a-dyin'", while the UK version uses, "Watch my daddy in bed a-dyin'" (as a result of an error by the music labels, certain online retailers sell the UK version but incorrectly identify it as the US version).
