"Weird Al" Yankovic is currently traveling North American performing for his Ridiculously Self-Indulgent, Ill-Advised Vanity Tour, one that he promised would not be business as usual. Living up to that promise, he recently performed Billy Idol's 1983 hit "Rebel Yell" live in Carmel, Indiana. No, not a parody of it, the actual song.
(He's also been playing Lynyrd Skynyrd's "Free Bird"!)
