The earliest line-up of the original Jeff Beck Group had Ronnie Wood on second guitar, with Jet Harris, formerly of The Shadows(the UK's analogue of The Ventures)on bass. Harris, who had depression and drinking problems, dropped out early, with Wood eventually taking over the bass slot. Further turmoil in the rhythm section saw drummers Clem Cattini(of the Tornados and countless sessions), Viv Prince(The Pretty Things), and Aynsley Dunbar(Mayall, Zappa, Bowie, Reed, Jefferson Starship)come and go, before they settled on Mick Waller.
Sunn amplifiers, one of the better known amp lines of the mid-60's to early 70's, was started by Norm Sundholm, bassist for The Kingsmen of "Louie Louie" fame, and his technically-minded brother, Conrad. As the Kingsmen hit the big time with 'Louie', and their subsequent 15 minutes of fame with "Money" and "Jolly Green Giant", Norm found that his rig was inadequate for the growing crowds; Conrad had the idea of combining hi-fi power amps with JBL speakers in a unique cab that he designed to increase the low end with less distortion, essentially making the eventual 200s model one of, if not the, first amps to be built specifically for bass, as opposed to a modified guitar amp. The
2000s was basically the first fridge rig. While they did issue guitar amps, sales of those lagged behind those for bass. Sunn just about led the pack in bass amplification(at least in the US)until Acoustic Control and Ampeg's SVT came along.
"Memo From Turner", a song often mistakenly attributed to The Rolling Stones, was essentially a Mick Jagger solo track, featured in the movie "Performance", in which Jagger starred. The most familiar version, as from the soundtrack, featured Ry Cooder on slide guitar, Russ Titelman on guitar, Randy Newman on piano, Jerry Scheff(The Doors, Elvis)on bass, and Gene Parsons(the later Byrds, and co-inventor of the 'B-Bender' for Telecasters)on drums...
There were two other versions recorded, one with supposed Stones' members' participation, along with members of Traffic(Winwood doing the heavy lifting on keys, lead guitar, and bass), Brian Jones(?), and Charlie Watts or Jim Capaldi on drums...
And the third, which appeared on the Stones' odds'n'sods compilation "Metamorphosis, which featured Jones, Wyman, Winwood and Capaldi again, along with Al Kooper on keys...
