Hank Williams, Jambalaya (On the Bayou)
Kingston Trio, Tom Dooley
Chuck Berry, Memphis, TN. The Lonnie Mack version sports three chords!
Seeds, Pushin' too Hard. If you remember this cheesy garage-band number, with its cheesy guitar solo, I'll buy you a beer.
Eric Clapton, Tulsa Time
Sir Douglas Quintet, Mendocino. This one goes out to Joe Odegaard.
Joe Cocker, Feelin' Alright
Beatles, Paperback Writer. Mostly just two chords.
UPDATE (2/17)
Mendocino Joe sends us to Frank Zappa's Camarillo Brillo. "She carried on without a comma . . . ."
