Who sings the song in the Gap commercial in which people are jumping around in slow motion?

If it's what I think it is, that would be Brian Setzer Orchestra, singing "Jump, Jive, and Wail." If you find that song and listen to it, and it sounds like the same one, let me know if I'm right! Here's another thought, back in the 90's when this commercial was being used, Gap may have used both the original Louis Prima version and the Brian Setzer version at different times, I seem to remember both. August 15, 2007: I wrote to gap.com last year to settle a bet with someone, and they informed me that the version of "Jump, Jive and Wail" used in their commercial was indeed Louis Prima's not the BSO.
