You just might want to loosen up a bit with some dancing so here is a clip of Pan's People, a group of females who would dance to a song on the BBC-TV music chart show Top of the Pops when the artist wasn't available to sing it live (or Memorex). (Think the Solid Gold dancers for those in the States.) This clip is the troupe dancing to Creedence Clearwater Revival's Green River.
And, of course, there's the even funnier take-off by French and Saunders' Pan's Indeedy People moving to Yellow River - with a long yellow cloth to boot.
Yellow River? Don't take me there.
