At 65, Weird Al still commands the stage like a natural-born rocker, with high kicks and the panache to pull off what few other artists can (including a fat suit).

During “Eat It,” a riff on Michael Jackson’s “Beat It,” audience members — many in Hawaiian shirts and sporting curly locks — were on their feet. Even a seen-it-all security guard danced. For “White & Nerdy,” Weird Al arrived via scooter, to the thump of Chamillionaire’s “Ridin’.” Father-son pairs, arm-in-arm, knew every lyric.
