If there is a jam session for Bo, it's likely to be a doozy. Think of it: With Bo Diddly laying down the signature beat, there's Jimi on lead guitar, trading riffs with Stevie Ray. Janis on vocals. Half of Lynyrd Skynyrd. L.B.J. over there whippin' up some ribs on the grill. If they're lucky, Lionel will break out into a vibe solo if we can get him out from behind the drum set. Perhaps, during kit changes, poetry readings by Kerouac and Ginsberg.
As for your questions, they are all good questions to which no one really knows the answers. It is fun to imagine, though.
