I know the one! It was 'James Brown - Sex Machine'. He keeps saying "Get upppppppaaaa...." because that was the only part he heard. I hope all this time later it is useful to you.
You tried to help... and help you did! I found a song called 'Forever and a Day' by 'State One'. That samples the music from the advert. Unfortunately, I haven't been able to find the link again, but I'm sure it would be easy enough to find knowing the name now. Thanks for your help.

Does anyone know what the music is that's used just before some programmes on BBC1. It's where everyone is jumping up and down in slow motion at some form of rave. Any ideas?
Go to http://www.members.lycos.co.uk/jaywick/ and select TV Themes from the left hand side. "Jaywick" will send you what ever theme tune you ask for fairly quickly.
