The reunion we have all been waiting for, Danny and Sandy, oops I mean John Travolta and Olivia Newton-John.  The co-stars of Grease will be singing together on a new album out for the holidays called, "This Christmas".  The original duet is called 'I Think You Might Like It'. 

The cd will also feature Barbara Streisand, Tony Bennett, and Kenny G.  Not only will you hear great holiday music, but you'll also be helping charity as one hundred percent of the proceeds will go to the Jeff Travolta Foundation and the Olivia Newton-John Cancer and Wellness Centre in Melbourne.

This is such a classic movie, you knew I had to throw a clip in:
