The party version did not have the music integrated due to a problem with the loader (we had to revert back to a system loader, which uses the 16k of top memory) so we had to strip out the music player as well (and incure a 10% cpu time penalty in the process).
We had a version later with the sound, but got victim of a HDD crash while doing it, had no backups of course, so that's the only version I could find.
I guess if I had the courage I could try to rip out the files and replace the loader, but that was so long ago, and I was not the one writing the loader in first place, so this may prove to be difficult.
In order to give you a hint about the party look and feel, you can find on the right side some photos taken during the party.
