Brian had quit/had his big breakdown after Summer Days and Pet Sounds-GV-Smile had never even existed?
They'd be in with The Mamas and Papas, Grass Roots, Turtles, Association, Rascals, and The Union Gap,...but not
anywhere near as cool as The Byrds, Buffalo Springfield, the Doors or CCR. Certainly, though, better than the Cowsills, Jay and the Americans, the Vogues and Jan and Dean.
They'd be 1/2 of what they are...and 1/4 of what they could have and should have been...if it weren't for mental illness combined with 2 entirely stupid idiots [in particular] impacting negatively on the creative growth patterns and on the heights never really achieved with anything approaching a true level of consistency.
