The Gregory Brothers + Key of Awesome

Two Internet-famous, meme-browsing musical groups share the spotlight tonight. The Gregory Brothers, best known for their appropriations of political debates and TV news interviews, make painfully catchy songs from Auto-Tuned snippets of dialogue. Prolific parodists Key of Awesome do the "Weird Al" thing, taking on pop, rap and rock hits from Macklemore to Mumford & Sons.
