We were friends from a long time back and we were in Montreux, in Switzerland. We own a studio there, so we're working there and he lives there. He just happened to be there, and he kept coming to the studio, listening to our tracks, and we were jamming to some of his old songs, and one day we were having dinner and after that we were going back into the studio to carry on with the session, and it just happened: he just said “oh, why don't we just fool around and get something started and see what happens?” And, you know, started playing the piano, and the rest of the band were there and we started putting something down and Under Pressure started to build.
