Captain, if that was directed at me for saying the Scott Walker Prom was duff - I wasn't doubting the talent of Scott himself, just those supposedly trying to 'honour' him!
Not specifically GG; I know his music has gone haywire these last 20 odd years (I couldn't listen to any of his modern day work) but his voice is wonderful.
PS I didn't see the programme you referred to, so you're more than probably correct there.
