In my favourite picture of Amy Winehouse, she’s holding a hoover. It’s partly the thought that Amy Winehouse did the hoovering, partly that she looked like that – hair aloft, fag askew, lids weighed down with liner – full-time. She always mixed the real and the unreal. Her voice, described in the New Yorker as a kind of ‘aural blackface’, belonged in several decades at once. Her version of ‘Valerie’ made the Zutons’ sound like a cover; the way she sang it, it could almost have been an original Motown song – the reverse of what Phil Collins once did to ‘You Can’t Hurry Love’. Detroit met Southgate somewhere in her voice.
