From Mateo's research this appears to be the ssme as the Music on Vinyl LP but without the incidental music. So a bit pointless but I am looking forward to seeing the full artwork.
He wanted to know the differences between the trunk lp and the music on vinyl lp.
Basically the trunk lp (and cd) is mono and was taken from the music and effects tape. It has the same versions of the songs as are in the originally released "short" version of the movie.
The music on vinyl lp (and silva screen cd) has the songs in stereo (including Gently Johnny which is absent from the short version of the film and thus the trunk release) and some of the effects and incidental music from the effects tape (in mono). There seems to be less incidental music on this release but I haven't figured out what's missing yet. This is actually shorter despite the extra song and longer versions of some songs.
Interestingly the MOV lp versions of Willow's Song includes extra lines that are missing from the short version of the movie but present in the longest known version. But the versions of the Landlord's Daughter and the Tinker of Rye have extra lines from this long version and additional lines that are not in any known cut of the film.
