Today I received via mail the Haunted Mansion complete movie soundtrack on two CD-Rs. I must say, it's a pity more of Mark Mancina's score wasn't officially released. There are some very entertaining presentations of "Grim Grinning Ghosts" and original themes written for the movie.
I'm rather glad I lost an eBay auction for this item a few weeks ago--it went for $57, and that's too much for 80 minutes of music. I then found the same soundtrack for $16 on this site. I couldn't pass up the opportunity. It's unfortunate that so many movie soundtracks are only released in incomplete form.
