His debut album remains one of the best in the history of the rock era. I think ego got the best of him after that however, and he pretty much self-destructed. Huge waste of great talent.
His first hit in the US was "If You Let Me Stay", followed by "Wishing Well", which stayed at #1 for like six or eight weeks, then "Sign Your Name". All this happened back in 1988-89, when my hair was still black.
