What's the license of Mortimer's Chip-disko?

[GNUAn]

I am creating album with various (not mine) house songs that are free (libre), then, I played SuperTux and Mortimer's Chip-disko sounds like house, I'd like to add it to my album, but I don't know what license it uses. (I know how to create house, but look at ZaurOrg, it has record label)

Oh, I will turn 20 in 2 days(0.0.6 was released on March 15 2004)

I'm not 20, Mortimer's Chip-disko is 20

Oh, thanks for the clarification! That's an interesting fact.

Hello @GNUAn, Mortimer's Chip Disko (chipdisko.ogg) is licensed under the CC-BY-SA and GPL by Lukas Nystrand (as Mortimer Twang). I don't know which specific license versions are used. There is licensing info for the music in the data/AUTHORS file.
