1) There was a cantina-type song that was featured in the Episode I and X-Wing: Alliance games. I'm guessing it could easily be ripped from the CD if needed. However, it had a very "AM radio" sound.
2) Several years ago the Lexus commercials used to feature an upbeat jazzy song. I thought it was VERY similar to the music for the Mos Eisley cantina, kind of like what they might have played if we'd stuck around for a third song.
