20 Shocking Things You Didn’t Know About Grease

Being Assertive

“Greased Lighting” is one of the more famous tracks from the movie. It shows the T-Birds all getting together around Kenickie’s car as a brand new motor is delicately placed in the front of the vehicle. Of course, it’s Travolta leading the charge with his charisma and underrated vocal performance.

As fate would have it, the song was not intended to be sung by Zuko. It was actually supposed to be a Kenickie song (sung by Conaway). However, Travolta reportedly disagreed with that sentiment and instead allegedly demanded to sing the song himself. This allegedly caused some tension on set (presumably with Conaway).
