That's right! We've just posted guitar chords and sheet music for the Cutie Mark Crusaders epic 80s-rock-ballad. Huge props to our own Moonlight Sonata, who worked out the sheet music (and without whom Everypony Sings would be in deep trouble). Thanks also to Bagpipe Brony for sharing his ideas for the chords.
Check out the sheet music here (via Google docs), and the chords here. Tabs for the squiggly-wiggly guitar (that's technical musical terminology, thank you very much) will be posted in the near future. Enjoy!
[Edit: We forgot to include a link to the tabs Shaico submitted. Our apologies for that! Check out his tabs here.]
