Sum 41 invited Mike Shinoda on stage during their Main Stage set at England's Reading festival on Saturday (Aug 25), where they belted out a cover of Linkin Park's classic track 'Faint'.
“Ladies and gentlemen, we have a very, very special guest with us tonight,” Sum 41 frontman Deryck Whibley announced before the band’s final song.
“Say hello to Mr. Mike Shinoda!”
Fans lost their shit, with a heap of them posting their excitement on the ol' Twitter.
As the track came to a close Whibley gave Shinoda a shout out and said: “Chester, we miss you.”
Shinoda also got the crowd singing - 'In the end' just like old times, pretty special stuff.
