The montage song from south park.
It's from season 6 episode 3 called: Asspen
Edit: I know there is a montage song in Team America but its slightly diffrent, THIS IS THE 1 FROM SOUTH PARK!
The episode where the song was in (asspen) was released Mar 20, 2002.
Team america was released October 15, 2004.
So it was used in South Park first!
Besides The makers of south park and team america are the same.
The day's approaching to give it your best,
and you've got to reach your prime
That's when you need to put yourself to the test,
and show us a passage of time
We're gonna need a montage! (MONTAGE !)
A sports training montage! (MONTAGE !)
Show a lot of things happening at once,
remind everyone of what's going on! (WHAT'S GOING ON!)
And with every shot show a little improvement,
to show it all would take too long!
That's called a montage! (MONTAGE !)
Even Rocky had a montage! (MONTAGE !)
In any sport if you want to go,
from just a beginner to a pro
You need a montage! (MONTAGE !)
A simple little montage! (MONTAGE !)
Always fade out in a montage
If you fade out it seems like more time has a passed in a montage
