I agree to some extent. There are definitely some questionable songs that written or performed by anyone probably wouldn’t be that great. But I can’t agree that anyone else other than the drug and booze addled stones could deliver albums like:
exile on main street
sticky fingers
Let it bleed
beggars banquet
obviously subjective but I really enjoyed the sometimes sloppy imperfect elements to those albums mixed with the perfect ones.
and yeah, poaching Ron wood from the faces was arguably the best move they ever made as a band.
edit
and of course I don’t want to see or hear any of that performed now.
