well, just speaking out loud and the obvious, the bit genies heard is used as a radio jingle for Outback Steakhouse. Went looking for a link or something, but can't find it.

But from what I remember, there wasn't much to it. The jingle pretty much goes like this:

mum.....mum.....mum.....everybody loves mum.....mum......mum.....even when she slaps your bumm...bummm.... everybody loves mum.....mum.....mum.....its a day for mum....mum....mum...

Whether its an actual song, I dont know. Will keep an eye out. Might be able to find it in a (gasp!) place like morpheus, if someone recorded the commercial.
