You can hear it start at 3:39 in the background, it's like the same tune on a loop and it carries on up until about 4:40
You can also hear it properly and loud at 5:22 in the background, I think it's the same song, if it's not does anyone know the title of this song?
Seriously I loved it when I heard it on Big Brother's Final Hour and this morning there was nothing on the telly so I just went through Sky+ and watched the Final Hour show again
I watch it alot.
