He`s one of those guys who writes big songs for other people such as Elton John, The Hollies, Leo Sayer, Diana Ross, Tina Turner and loads of others. Chances are most people will have heard his work but just not realised who he is. Bargain at 99p. I`d have suggested the two on one cd of `It Never Rains In California`/`The Free Electric Band` but you already have one of those. There is a cheap greatest hits compilation I believe.
Other artists to try? Maybe stuff like The Sutherland Brothers or Gallagher and Lyle.
