#5 – John Travolta & Olivia Newton-John – “Summer Nights” – (1978)

This was a #5 hit on the Hot 100. That’s right, John Travolta has a top five hit. Grease is the best movie adaptation of a musical ever (that is both my opinion and fact). It has a lot of popular music in it, but this was the best. I do believe that this is the #1 karaoke song of all time as well – name a more popular duet. It’s hard to do.
