Sam Smith surprised by Radiohead's James Bond song

Spectre songwriter Sam Smith was shocked to discover Radiohead had released a track they wrote for the James Bond movie.

Over the festive season (Dec15), Radiohead frontman Thom Yorke gave away a song the band had written for the Spectre theme, which was never used.

Sam's effort, Writing's on the Wall, was ultimately used for the theme, and the Stay With Me singer and his co-writer pal Jimmy Napes won the Best Original Song prize at the Golden Globe Awards for the track on Sunday night (10Jan16).

During a press conference after the show, Sam admitted he was thrown by the release of an alternate James Bond song, and has not checked it out.

"Was I shocked?" he said. "I was a little bit surprised, not gonna lie, little bit surprised... but I actually haven't listened to it personally because I did the Spectre theme song."

Radiohead wrote on the track's Soundcloud.com page, "Last year we were asked to write a theme tune for the Bond movie Spectre. Yes we were. It didn't work out, but became something of our own, which we love very much."

Sam told E! News he was amazed by the Golden Globe win, saying, "I'm in complete shock to be honest with you... I just didn't think it was going to happen tonight. We've been here just enjoying it, just looking at everyone, it's just weird... It's not our world but we feel very welcomed, which is beautiful."
