The pitch at which girls screamed once the Wanted came onstage on 'The Tonight Show With Jay Leno' probably could shatter glass. The British boy band performed their massive, ubiquitous 'Glad You Came' on the late night staple, much to the delight of women everywhere.

The Wanted took an interesting approach to the performance: Whenever one of them had a solo, the rest would fade into the background. When the chorus hit, they all joined in, though they lacked the choreography you'd expect from such a dance-oriented song. When the second chorus came around, there was a slew of hand clapping from the guys, but that's as far as it got.

That is, until the closing of the track. Heartthrob Max George summoned screaming girls from the audience onto the stage, where the band had a dance party with the crowd for the conclusion of the song, even letting some lucky gals sing the last lines. Yes, we are jealous! Check out the video below.
