Amy Winehouse and Mark Ronson to write and record Bond theme tune

Amy Winehouse and super-producer Mark Ronson will write and record the theme to the new James Bond film next week.

Ronson arrived at the 'Rehab' singer's London home on Thursday to take her recording equipment to his country retreat -- where the pair will put together the biggest song of their careers. It will feature in 22nd Bond movie Quantum Of Solace, which is out in October.

A source said: "Amy and Mark are really excited. They see this as the biggest thing they have ever done.

"Mark collected her clothes and guitar to take to his place. She will join him soon and they will lock themselves away to write and record the song.

"They have no idea what they’re going to do. In true Amy fashion, they’re going to busk it.

"But I’m sure it will be brilliant. The new Bond film is supposed to be really dark so Amy will fit the bill perfectly."

Amy, 24, has recorded her most successful material -- including Valerie, and Grammy-winning hit Rehab -- with Ronson.

Ronson has also worked with the likes of Lily Allen, Christina Aguilera and Robbie Williams.

The source added: "They’ve got a great understanding. She comes up with a basic idea and he makes it happen."
