In terms of sheer musicianship, I would have to go for:
Paul- bass, guitars, piano, vocals etc
Abe on drums- solid, flamboyant, fun and good vocally
Laurence Luber- fantastic musician, if slightly clean for my taste...
Wix, naturally, on keys and musical overseeing
Brian Ray- second guitar/ bass/ vocals
Sorry, no room for Denny Laine. Despite his importance to Paul during the early years
and on into Wings, he was never up to the level of musicianship of the guys named above.
Nice guy, but sorry DL!
