Sometimes, James Corden’s Late Late Show comes off like some kind of extended fantasy-camp wish-fulfillment experience for Corden. Case in point: Last night, Corden got to briefly join one of the most popular bands in the world. Fellow Brits Coldplay were on his show to flog their whatever new album A Head Full Of Dreams. On a flower-strewn stage, they did an energetic and Corden-free version of their single “Adventure Of A Lifetime.” But they also played the album’s title track, and on that song, Corden joined them on piano and looked very, very excited to be there. You can watch both performances below.
