"This Is the End" is a song from Mickey, Donald, Goofy: The Three Musketeers, singing for the Troubadour to Donald. It is sung to the tune of Beethoven's 5th Symphony.
Troubadour: (with chorus) This is the end! (2x)
You've seen how Donald gave his friends the double-cross?
He's in retreat and Pegleg Pete is now the boss!
All France in flame! (Chorus: It's all in flame!)
We curse his name! (Chorus: We curse his name!)
With Donald Duck, (with chorus) the blame!
That Donald Duck has left poor Mickey Mouse to drown (Chorus: He let him drown!)
And Goofy trusted him, but Donald let him down (Chorus: He let him down!)
(with chorus) We all berate him, because we hate him
He is a traitor, vacillator
He's a lousy second-rater
He's a quizzly coupe en-sizzling
He really should be russetated
How he quivered, shaked & shivered (He's completely lilly-livered!)
Mangy mallard! (He's a coward)
Donald's destiny has soured, it's the end!
This is the end!
The ever-laughing end!
