The original version of Amy Winehouse and Mark Ronson's hit single
was a slowed down R&B version of the tune. Recorded in December 2006, despite initial reservations of it sounding a bit "cheesy," Ronson later realized it was one of the best vocals Winehouse had ever done and handed it over for inclusion on her posthumous album, Lioness: Hidden Treasures
. He told NME
: "When we started the song it had a kind of '60s Curtis Mayfield arrangement… it's a little more jazz tempo and it's super soulful. I still like the original version more, and when you heard her do it live, it's much closer to that arrangement."
