All bets are off because its now official, singing superstar Sam Smith has recorded the theme song for upcoming Bond movie Spectre.The track, which will be released shortly, is called Writing's on the Wall. Speaking about the announcement Sam said: "This is one of the highlights of my career." It certainly is because he's now joined major talents like Adele, Madonna, Sir Tom Jones and of course Dame Shirley Bassey who've all sang for 007. Sam, who had previously denied being selected for Bond, revealed his involvement to Radio 1's Nick Grimshaw, saying "I'm so relieved to actually talk about this, this has been a top secret mission of my own."
