When it comes to musicals, there are some that have crossed over and become pop-culture phenomenons - and 'Grease' is probably the best example.
Whether people love it because of the songs or it's Olivia Newton-John and John Travolta's iconic performances, the one thing that everyone remembers is the costumes - Danny's T-Bird leather jacket, and Sandy's bright-yellow cardigan.
And sure enough, that's exactly what John Travolta and Olivia Newton-John wore at a recent event yesterday and just so happened to be the first time both of them were in costume together since the movie.
The event was part of a special 'Meet-n-Grease' sing-a-long screening tour of the movie, with Travolta and Newton-John joining the audience with such tracks as 'Hopelessly Devoted To You', 'Sandy' and, of course, 'Greased Lightning'.
Newton-John and Travolta have reunited many times since the 1978 hit, most recently at the 40-year anniversary of the movie. In fact, just last month, Newton-John sold the iconic leather jacket costume at the end of the movie to support her cancer foundation, with the jacket selling for $243,200 while the leather pants sold for $162,500.
