There was the extended version, that was introduced early on, in season 3. Either that or some time after the Thunder Zords were introduced.

Happy 26th anniversary, MMPR.

AMV-makers, to your Movie Maker programs!

Sweet. Now where are the verses? (You did know there was more than just the opening riff and chorus, right?)

“Ahahahahahahaaaa… ha.” Nightmare Moon paused a moment, looking around. “Hmmm. Now, where did that scepter get off to?”
 
 
Meanwhile, in Canterlot.
 
“Ai-yi-yi-yi-yi! Celestia, we’ve got an emergency!”
 
“Cadence, I don’t have time for -why are you wearing a mariachi outfit?”
 
“-Why do you have a jar on your head? Never mind. Nightmare Moon has escaped and is attacking Equestria, sort of.”
 
“Quickly, teleport to us six overbearing and overemotional ponies!”
 
“… Please tell me this was “plan B”.”

NMM: AHHHH! After a one thousand years I’m free! It’s time to bring Equestria into an Eternal night!

not bad!
