Specifically there was a track that Mark & Lard used to play on daytime Radio 1 (late nineties/early noughties) - it was about 2 minutes long with female vocals and sounded like music from different adverts being played through a blender. It was utterly excellent and I swore I had an mp3 of it somewhere...but no

A thousand indie points to the person that finds it! (and posts a helpful link)

Anything else like that would be great - I don't think it was Melt-Banana or Boris but I'm happy to be corrected!
