Listen to Coldplay on iHeartRadio

As a fellow Brit in the Big Apple this weekend, Chris Martin did his best to make Andrew Garfield feel welcome. 

On a new episode of "Saturday Night Live," the Coldplay frontman stepped in for Garfield's girlfriend and Amazing Spider-Man co-star Emma Stone to show him the right way to do a big-screen kissing scene. 

Of course, Martin was also there to play some new Coldplay songs.  He and the guys took the Studio 8H stage twice to perform their hit single "Magic" and the recently-unveiled track "A Sky Full of Stars."  Both cuts come from Coldplay's upcoming album Ghost Stories, which is due out May 19th.  And before that, the band will be returning to NBC for the concert special "Coldplay: Ghost Stories," set to air Sunday, May 18th at 7:00 p.m. Eastern.
