We should have folded after Dick Pym left for Bolton.Are we being a bit precious here, given that we all support Exeter City with it's ever evolving line-up ? ? ? ?
Anyway, I agree it's a pretty nuanced situation - the thing with Quo is that as said above they were pretty much a duo with backing band now so it seems a bit strange for them to carry on in their original guise. I found Queen carrying on without Mercury to be a bit odd too - although when Paul Rodgers filled in they appended his name to the band to show he was a "guest".
But then again as also said above, there may have been people calling for AC/DC to give it up after Bon Scott died but then Brian Johnson came in and didn't exactly do a bad job (in between stints commentating on TMS).
