Amy's collaboration with Mark Ronson on his track ‘Valerie’, a cover of The Zutons 2006 hit, which secured Amy as one of the biggest names in the industry.

Despite being known for her soulful jazz voice, Amy lent her vocals to the track for Ronson's 2007 covers album 'Version'.

Ronson was initially unsure that Amy's vocal style would suit the song, but he quickly realised his concerns were unfounded.

He said: "She went into the studio and tried it. I loved it."
