The Rainbow Dash redemption scene in MLP S2 Episode 2. The music has been replaced with the Star Wars Episode I OST, composed by John Williams and performed by the London Symphony Orchestra.

Part of my MLP Star Wars OST project, an experimental series of videos featuring scenes from MLP accompanied by the Star Wars OST .The purpose of this project is to see what MLP might be like if William Anderson (the composer of the fantastic MLP OST) were given a full orchestra or higher-quality samples to work with; it's also just for fun! See other videos in this project below. =)

Tracks used:

"The Racer Roars to Life"
Star Wars I: The Complete Recordings (Ripped/assembled by GGCTUK)
Performed by the London Symphony Orchestra
Composed by John Williams
