Van Halen Performs 'Panama' at the 2015 Billboard Music Awards: Watch
Van Halen made a rare live TV appearance at the 2015 Billboard Music Awards on Sunday night in Las Vegas.
The hard rock legends took the stage after Taylor Swift gave the world premiere of her "Bad Blood" video (featuring everyone ever) to deliver "Panama," one of the highlights from 1984 and one of their most enduring hits.
It's hard to say what was better: David Lee Roth's Newsies cap or his slithery onstage theatrics. Watch the remarkable performance below.
