The opinion that John Bonham "was great" is one not universally held. Buddy Rich dismissed him, and reportedly did a great (mocking) imitation of him. Buddy also referred to Ginger Baker as a "clown". Tough audience! His comment on Ringo Starr was that he was "adequate". Coming from Buddy, that’s almost a compliment!
Well-known studio drummer Jim Keltner (Ry Cooder, John Lennon and George Harrison, Bob Dylan, Bill Frisell, hundreds of others) has said he wishes he played more like one of my favorites, Roger Hawkins of The Swampers (Fame Studios house band, heard on hundreds of records including all the Jerry Wexler-produced Atlantic albums made in that Muscle Shoals, Alabama recording studio).
