Gregory Brothers singing Double Rainbow
The Gregory Brothers of Auto-Tune the News fame have turned the new famous Double Rainbow Reaction video into a song, finishing with a vocal rendition from the band. Wow wow oh my god. You should of course watch the original double rainbow video below, and many more of Yosemite Bear's videos about living in God's own country in Urlesque's earlier Yosemite Bear coverage. You should also listen to the Double Rainbow Connection song, a duet by Yosemite Bear and Kermit the Frog. When I listened to this, I cried unicorns.

Finally, you should check out Urlesque's interview with Yosemite Bear.
