Hello, the track is by Dead or Alive and is called You Spin Me Round.
The singer was Paul King who later appeared on TV.
I think he owned Probe Records in LIverpool in the 80's.
The latest one I've seen is the little boy playing football (and knocking various things over) to the tune of 'My Perfect Cousin' by the Undertones.
Previous adverts in this excellent series that I remember were 'Electricity' by OMD (that's Orchestral Manoeuvres in the Dark to you young folk) (boy dancing with toy robot) 'Ca Plane Pour Moi' by Plastic Bertrand (girl jumping on bed) Wasn't there a Slade one? Anyone remember any others?
I've just got to say that the singer with Dead Or Alive wasn't Paul King - it was Pete Burns. Paul King was lead singer with King, probably best known for "Love And Pride". I'm not convinced either of them owned Probe Records either!
Also, in reply to Trilobite, my fave Clarks ad is the one where the little girl is dancing to "Yes Sir, I Can Boogie" by Baccara. They're cute ads - and I don't even like kids!
