Didn't one of the Madness chaps play piano on some of Moz's tracks?Maybe it's worth noting that his connection to Madness was based on something a bit more substantial than "a crush".
Morrissey admitted to being a Madness fan, and honestly that's hardly surprising. They were funny, unusual, political or, as he put it, not "standard pop fare".
In 1989 he started working with Madness producers Clive Langer and Alan Winstanley, with Langer quickly being drawn into "Morrissey World", as he would call it. (He basically took the spot previously held by Marr and Street, acting as Morrissey's buffer from and link to the outside world.)
They were his initial connection to the band, which led to Suggs and Cathal Smyth doing backing vocals on some songs and Bedders playing bass on Kill Uncle.
Madness themselves also had a history of clashing with their own crowd. In their early days, there was an incident of a support act being exposed to racist chants from the extreme right-wing skinhead portion of the audience and also people doing the Hitler salute.
