It’s a dilemma for these bands. Who are we to say they shouldn’t be out there. There’s a demand after all. I wouldn’t go and see that line up now, but each to their own. I suppose for the likes of me, they answer would be, ‘play they albums then!’
What I do think is perhaps a more upfront way forward is to do what I think Gene Simmonds has talked about and set up an officially sanctioned band when none of the original members are fit to play - I guess it then becomes a cash-cow that can be milked for eternity! Perhaps it’s a bit easier for Kiss, what with the make-up it would be a piece of cake as long as the line up sounded ok ;-)
I’ve generally maintained I don’t really wanna hear songs recorded by a 25 year old sung by 75 year old original member. With some exceptions I’d be happy to hear them sung by a different 25 year old who has a similar voice.
