Well, it's hard to believe but this year marks the 40th anniversary of the movie Grease! So with that anniversary, there will be new DVD's coming out with all kinds of extras on them that will take us behind the scenes of the movie and the music. In anticipation of that, Barry Gibb has released the original demo for the song Grease. He said it only took him a couple of hours to write the song. No it's not him playing the piano but it is him clapping along to the song. I like his version. Granted he sings backup on the original with Frankie Valli, but I like this version too. Check it out. What do you think?
