Didja hear what transpired when The Jeff Beck Group played The Fillmore in late-68? As Jeff took off on a mid-song solo, Rod meandered back to the guitar rack, picked one up and strapped it on, and slowly made his way back to the front of the stage, strumming as he walked. Jeff noticed him, stopped playing, and walked up to his mic, uttering the following: "The damned thing's not even plugged in. Bloody wanker." Rod sheepishly made his way back to the rack, removed the guitar and put it back in place. How humiliating.
On that debut album he had Micky Waller playing drums, and Micky did that tour as well. How Jeff could have gone from the tasty playing of Micky Waller to the playing of Cozy Powell---and later the even worse playing of Carmine Appice---has long mystified me. But in his final years he had the astounding Vinnie Colaiuta in his band, so all is forgiven. ;-)
