British-irish boy band the Wanted wowed a more mature crowd during their post-Billboard Music Awards performance Sunday night at Lavo at the Palazzo in Vegas. They performed their new single, “Chasing the Sun,” and their hit “Glad You Came.” Afterward, Redfoo from LMFAO took the stage, and the Wanted singer Tom Parker (pictured) hopped onstage and did LMFAO’s trademark “shuffle” dance with the band. The party-loving musicians didn’t leave the club until 4 a.m.
