Weezer made their live comeback after Rivers Cuomo's near fatal bus crash in Florida last night (January 20) and were joined by a very special guest on stage - Hayley Williams.

The Paramore singer joined the indie-rockers on stage at the Florida State University in Tallahassee for a storming rendition of their hit 1995 single 'Say It Ain't So'.

You can watch the video (from the very top row of the arena) below.

Earlier on in the night, in a tweet directed at Rivers Cuomo, Hayley Williams said: “I’m almost to FSU, kinda gotta pee. But I’m going to write it off as being way anxious. See you soon!”

Afterwards, the 21-year-old wrote: “That show was ridiculous! I won’t ever forget the first time I sang in 2010, because it was with Weezer!”
