I must agree with Nockster, Baryburbs. Roger is limited in his musical songwriting ability. With the exception of Money, most of his music is like slow rap, a variation on 2 notes ... while any of PF's great songs the chord progressions were added by Dave (and some Rick). Even Mother ... great song, but musically it's 2 notes... without Dave's piece, boring ... like Pigs on the wing. Daves numbers have alot more variation, although he's limited to about 6 - 8 chords. Still 3 times the music as Roger.
