Longest running television commerical

was for a set classical music records featuring an actor named
John Williams (not the composer)

In this commerical he asked "Do remember this song as
'Strangers in Paradise'? Well, it is actually Polovetsian Dance Number 4 by Borodin."

This commercial was satirized by comedian Robert Klein in the 70's with "Every song ever recorded". I believe this is on his "Child of the 50's" CD.

And with DVD and next generation HD-DVD, this will be possible.

This is the sort of stuff that only people over 50 know now.
