AKA Steven Nason & Steve Heart.
"Keyboards were shared between another Madness associate, session pianist Seamus Beaghen, and Steve Nieve of Elvis Costello’s Attractions (real name Steve Nason, renamed ‘Steve Heart’ by Morrissey on Kill Uncle’s inner sleeve)."
From Julie Hamill's Clive Langer "15 mins" interview (regarding Kill Uncle):
"J: There was a notable shift from guitar to piano in this album.
C: I got Steve Nieve in and quirked it up a bit. But it was based on Mark Nevin’s guitar parts that he played really well. He probably would have been more inclined to do a Fairground Attraction kind of thing, and I wasn’t excited by that. Mark seemed to like everything we did, I never really argued with him. I just pushed it down the direction that I imagine the record should sound like."
Steve plays piano on the Jonathan Ross Show when Morrissey sings "I've Changed My Plea To Guilty" (1990).
English keyboardist, born 19 February 1958, London, UK.
