Mark Ronson is in trouble.
It's summer 1998, and he's hunched over the turntables at New York's venerable VIP bar, Spy.
Ronson is there to DJ for Prince, the Purple pipsqueak of funk. It's going well, until he pulls Michael Jackson's Off The Wall from its sleeve, ready to drop the 1979 disco classic Don't Stop 'Til You Get Enough.
Suddenly, someone's tugging at his arm. It's the rapper Q-Tip, and there's an uncommon urgency to his voice as he shouts: "No! You can't play that. Not in front of Prince!"
Remembering the star's rivalry with Jackson in the 1980s, Ronson whips the record off the decks. But that leaves him with a problem.
