Man have you guys got it wrong ;-).
1- Willie Dixon. He not only invented Rock 'n' Roll bass playing, he wrote many of it's early songs. Played with Chuck Berry, Howlin' Wolf, and Muddy Waters.
2- James Jamerson. Motown's bassist, and Paul McCartney's model for bass playing. How can you nominate Paul when he took his style from James?!
3- Jerry Scheff. The best bassist I have seen live, playing with T-Bone Burnett. He also played with both Elvis' (Presley and Costello), Dylan, Roy Orbison, Richard Thompson, and hundreds of others.
4- Joey Spampinato. When Bill Wyman left The Stones, Joey was Keith Richards' first choice as replacement. Joey turned him down (!), preferring to stay in the REAL Best Rock 'n' Roll Band in the world, NRBQ.
5- Carol Kaye. Played on recordings of The Beach Boys (think about all those great bass parts), The Doors, Frank Zappa, Ray Charles, Phil Spector, Simon & Garfunkle, and thousands (literally) of others.
