I missed the chance so I looked up spoilers for the new episode which gave us Raripunk and I love it. And recently when I was attending my youngest nephew Zai who turned 3 we were watching the minions movie and that reminded me of a song that I learned from a Harry Potter fan music video once. I know it's from the movie Hair (it's a movie about...hippies? I never saw it)
So thought how about an ironic/fitting song for Rarity's new look.
