Help! Music in Full Circle?

[PlutoniumTangent]

I was wondering if anyone knows what the music is playing near the beginning of the SG-1 episode Full Circle, when Colonel ONeill is stepping into the elevator. Its a mixture of the typical SGC music plus... another tune that I know ive heard before. That 'other tune' is mostly what im curious about.

Halp please?

I could be wrong though but i've had a decent look about
