Goodbye Yellow Brick Road would’ve been better slimmed down, but getting it to a single, vinyl album would’ve been tough.
Quadrophenia is a great double album and Tommy isn’t bad either (I’m not a Who fan boy BTW).
I think The Wall could be shorter, but again, there’s more than a single album’s worth.
Physical Graffiti is one of my all time faves, but they should’ve released the HotH tracks with that album, as that would’ve been epic.
