Hayley and Gerard Way have both had the immense privilege and honor of performing with Weezer

i feel like Hayley's fangirling on the inside lol

LOL at that riff, Rivers is like "HAILEY LOOK AT WHAT I CAN DO."

Hayley looks so tiny

Thank god rivers actually moved around on stage for once

My god she's tiny

i know this, but people look for Paramore more than they do for Hayley

This truly is an example that Weezer, unlike any other bands, has endured through the years. Having the opportunity to play for 16 years, other new bands look up to them.

and why is everyone commenting about HAYLEY?! this is RIVERS' SONG. he's the one singing almost the entire thing, and rocking on an incredible guitar solo. hayley's voice is like background noise compared to rivers rocking this like the true champ that he is.

i still can't understand why there isn't a studio version of this shit.

Isn't it so symbolic that Rivers sings the part directed to his father on his own.

Dear Daddy, Seeing Rivers and Hayley on the same stage singing "Say it Ain't So", I could have dies happy right after.

My god, My favorite song by my favorite band featuring my secnd favorite band's vocalist! The dream...

Hayley will for ever be my celebrity crush.

Hayley's voice is just amazing. She sounds just like an angel <3

IT SEEMS LIKE A WEEZER CONCERT WOULD BE A HUGE SING-A-LONG. DAMN I WISH I COULD SEE THEM. OTHER BANDS THAT I HAVE SEEN...ABOUT 15-20 DIFFERENT ACTS (NOT A LOT), HAVE HAD LIKE 3 OR 4 SONGS THAT THE WHOLE CROWD GOT INTO. EVERY SONG BY WEEZER IS PRETTY MUCH AN ANTHEM AND EVERYONE WHO IS A BIG FAN OF WEEZER KNOWS ALL THE LYRICS TO PRETTY MUCH ALL THEIR SONGS. GREATEST BAND OUT OF THE 90'S FOR SURE IN THIS STYLE, ROCK.

this performance is so epic how did I not know this existed until now

Goddamn Hayley is cute. Pretty solid performance

I think my computer just broke with the amount of awesome in this video.

She rocks! Has great stage presence
