My apologies to our international readership, but this clip was too good not to share - even though it will only play for visitors from the United States.

Olivia Newton-John joined the cast of GLEE this week for a new version of her iconic song Physical with Jane Lynch (who plays evil cheer squad coach Sue Sylvester in the show.)

UPDATE: Heroic reader Mike was nice enough to share the YouTube link of the video with us, for all of our international guests! http://www.youtube.com/watch?v=thlogramihg -- thanks, Mike!

The song itself is also available for purchase on iTunes.
