Remember John Parr's classic 1985 song 'St. Elmo's Fire (Man In Motion)'? Well, it's now a song about Denver Broncos quarterback Tim Tebow.

And it was John Parr himself who changed it up.

The song was originally written for Richard Hansen, a wheelchair-bound Canadian athlete who was giving inspirational speeches.

But of course, it became the theme song to the classic 1985 Brat Pack flick "St. Elmo's Fire", starring Rob Lowe, Demi Moore, Andrew McCarthy, etc.

And now, it includes such lyrics as...

Gonna be a man in motion

All I need's my Broncos team

Take me where my future's lyin'

Tim Tebow's Fire

--And...

I can climb the highest mountain

These Broncos can't be beat

I can feel St Elmo’s Fire burnin' in me

Listen to the song in all its glory:

And here's video of Parr doing a much different acoustic version on ESPN a few months ago:
