Star Quality was an English 80s game/talent (ahem) show hosted by Gyles Brandreth (remember him? you will) and an Amazonian named Beverly. They only made 6 episodes and you can see why - although there is a pretty outstanding Thriller impression about 4 mins into it:
I saw that video on Charlie Brooker's Screenwipe - Brooker is hilarious -and not just for co-writing Nathan Barley (http://www.trashbat.co.ck/) with Chris Morris. Although any excuse to post it - Embedding is disabled but check out Nathan Barley's Sex Rap- you could learn a few sweet moves. And some kindly youtube user collected all the episodes of Charlie Brooker's Screenwipe in a playlist for you to peruse if you so desire. Not a bad way to spend a couple of hours if you get snowed in. Or really lazy.
