This would have to be one of my favorites now. Also notice something about the audio this time? I've slightly panned the mane 6 voices. Fluttershy and Rarity will be heard mostly through the left ear, Twilight and Applejack through the right ear, and Pinkie and Rainbow in the center. Enjoy the experience.

Applejack - Alto 2 (Lowest part)
*Bass Line
Twilight Sparkle - Alto 1 (Second Lowest Part)
*Bums
Rainbow Dash - Soprano 2 B (Third Lowest Part)
*Lead Vocals
Pinkie Pie - Soprano 2 A (Third Highest Part)

And Fluttershy - Soprano 1 A (Highest Part)
*Ahhs and Bagpipe solo *Melody in choruses*
