With the exception of Jack Bruce, I can't imagine that any of these players wouldn't have sounded better with a normal scale bass- you know, physics and all that. I imagine that none of them would have any problem playing one, either- we sure know McCartney didn't.
This a totally laughable comment. Even Jack didn’t like his sound from that period. We used to call it his “tuba tone”. Seriously, it was about as appealing as a can of farts.
