In case you hadn't noticed, or aren't on his mailing list, Mark Vidler, the king of the mash-up, has come back from the wilderness with an entire album's worth of brand new cut-n-paste magic. (Well, it's a fairly short album but no shorter than at least one KC and the Sunshine Band album, as I recall.) It's available on his website for your downloading pleasure.
Which is all you need to know.
