Commercial Breaks & Beats

Just seen a trailer for Big Brother's Big Mouth on Channel 4. I am desperate to find out what the music is that has been used in the background. It sounds same/similar as the music that was used on a recent Lost Season 1 catch up trailer.

This one is really bugging me. Can anyone throw any light on this?

Actually the trailer in question is for Big Brother's Big Brain.

Silly Me!

Actually if anyone does know the music for the Russell Brand trailer could they tell me. Y'know the organ-y sounding one that you can't hear that clearly. Cos Brand is cavorting so loudly.
