Radiohead may be one of the biggest rock bands of our time, but that doesn't mean they're perfect! The British guys had a few flubs during their first of three nights at London's Roundhouse as part of their world tour, which made for some funny moments.

First, guitarist Jonny Greenwood came in with his guitar a little too early during the band's performance of "Nude." Watch that above around the 0:40 mark, as Thom Yorke gives him the side-eye while the audience bursts into laughter.

The second screw-up in the show was solely the crowd's fault, where their excitement caused them to start a “Paranoid Android” singalong too early. “Oh no, no no no no no. Calm the fuck down," Yorke jokingly tells them. Check that LOL-worthy moment at the 3:55 mark below:
