Excellent idea and thread, Groovy!
A couple I'll start with, that also have a little variation.
The Allman Brothers Band (w/ Duane, Dickey, Barry)
Lynyrd Skynyrd (w/ Ronnie Van Zant, Allen Collins, Steve Gaines)
The Outlaws (w/ Hughie, Billy Jones, Freddy Salem)
another one, in a similar vein...
Lynyrd Skynyrd (w/ Ronnie Van Zant, Allen Collins, Steve Gaines)
The Outlaws (w/ Hughie, Billy Jones, Freddy Salem)
Molly Hatchet (the original band members)
I'll probably be back with many more, and as often as possible, too!
