This will wake you up...
Wee Papa Girl Rappers were twins, Sandra and Samantha Lawrence (Total S and TY Tim), formerly backing singers for Feargal Sharkey, who had a few minor hits in the late 80s. Heat It Up (made with 2 Men And A Drum Machine) hit number 21, the double trouble rapping and chanting riding on a 1988 club rhythm (and coupled with a Kevin Saunderson remix). It got them on Top of The Pops. Follow up Wee Rule went top 10.
The version at the top is a recent re-edit from SanFranDisko and comes as a free download. I rather like it.
