But Procol Harum are one of those bands who "suffer" from having had one huge hit to the extent that people think that's all they ever did.
AWSOP was their first single,but wasn't on their first album - they'd already moved way beyond it. And it's a great song, of course, but it's nowhere near their best work. If you like AWSOP, you should definitely check out "Homburg", "A Salty Dog", "Grand Hotel" and "Pandora's Box"...
