I checked Oddworld-Web. If it's on there, it's not advertised in the Media section.
I've got three of the tracks from the Abe A Gogo Soundtrack here:
Track 01
Track 03
Track 04
You must all praise Xavier for these, though.
EDIT: You
must right-click and select 'Save target as...' owtte.
EDIT: I've changed the addresses, just in case you needed to know.
