Sam Smith records theme song to new James Bond Movie, 'Spectre'

Sam Smith announced he has recorded the theme to the new James Bond flick, "Spectre."

"This is one of the highlights of my career," the British crooner tweeted Tuesday. "I am honored to finally announce that I will be singing the next Bond theme song."

Smith told BBC Radio 1 he'd recorded the song in January ("the quickest song I have ever written") and had been trying his darnedest to keep it hush-hush ever since

The song, called "Writing's on the Wall," will be released September 25. The movie comes out October 26 in the United Kingdom and November 6 in the United States.

The singer said he wrote the song with Jimmy Napes, with whom he penned the monster hit "Stay With Me."
