top 5 of the lesser known ones (relatively speaking), and in no order:
Bron-yr-Aur (not Bron-y-Aur Stomp, the instrumental off physical graffiti)
The Rover
Going to California
Ten Years Time
Achilles Last Stand
actually fuck it they're all good, but those are a few of my favourites that aren't the "predictable" ones, if that makes ANY sense...
