This is one of those songs which started out in the US and was recorded by a British band who had the bigger hit in the UK albeit this time with an altered lyric. Unusually the hit US version by The American Breed, which I think I prefer, also reached the UK charts. In the video below (set to the recording I would suggest, but with added screams) they were obviously hamming up the miming.
