Song played on Radio 1 at 1:00 on Sunday?

[MrCarnival]

I was listening to BBC's radio 2 yesterday afternoon at 1:00. They played 'The Hills are alive with the sound of the music' but it wasn't the original version played, was some sort of mega mix.

Can anybody tell me who it was that sung that song, or where I can listen to it again? Thanks in advance.

It was "The Disco Sound Of Music" by Showstoppers 81. If you find a downloadable version, I'm looking for it, too!
