More soundtrack...addittional songs?

I've never seen the motion picture but on Wikipedia it mentions two songs hinted at in the movie that were not on the soundtrack.

From Wikipedia:

Soundtrack from the Film More is Pink Floyd's first full-length soundtrack. The film More was directed by Barbet Shroeder; in it, two songs can be heard that were not included on the album: "Seabirds" and "Hollywood". The album actually comprises the other music used in the film, sometimes in a completely different form.

Does anyone know if studio versions were recorded for these songs? Were these instrumental tracks or do they have some vocals? Does anyone like them? Do you think they would ever turn up as bonus tracks on future More re-issues?

Seabirds is actually a pretty cool track. Roger sings the shouty rock-out verses while Dave croons the gentle chorus "I can hear the sound of seabirds in my ears..." Hollywood is an instrumental piece composed by Gilmour. The only versions available are those that play (under dialogue, sadly) in the film.
