I think the process was we were all drunk in the studio, and just for fun we were playing all sorts of old songs - I remember a couple of Cream songs - and whatever came into our heads, and I think David said, “look, hang on a minute, why don't we write our own?” I think he started on piano. We got this backing track down, and we got the riff and we got the bass thing together, so we had this pretty good backing track, and Freddie and David would go in and have a go and just sing what came into their heads but one wasn't allowed to listen to the other, and it was quite amusing and this sort of went through the night and then we had this sort of strange track the other day.
