Mark Ronson pays emotional tribute to Amy Winehouse as he reunites with her band in Camden for one-off concert marking 20 years of Back To Black

He helped Amy Winehouse create the album that turned her into a global superstar.

But 20 years after the release of Back To Black, Mark Ronson has admitted he did not grasp ‘just how insane’ her talent was at the time.

The producer appeared visibly moved as he reunited with Winehouse’s former band at the Roundhouse in Camden on Wednesday night for a one-off concert celebrating the record.

Taking to the stage in a blue velvet suit, Ronson told the audience: ‘I only know Camden through the eyes of Amy, so here we are, we’re in Amy’s house right now.

‘Amy’s musicality, she was like a monster. I definitely want everyone to know that.

‘I don’t even think I even realised at the time what an amazing lyricist she was.

‘She wrote so fast, I didn’t have time to realise just how insane her talent was.’

Ronson, 51, produced six tracks on Back To Black, including Rehab, You Know I’m No Good, Love Is A Losing Game and its title song.

He added: ‘It’s crazy that six songs made in a fit of furious musical infatuation would matter so deeply to so many people 20 years later.’

The musician told fans he understood how much the album had come to mean to them, saying: ‘I can’t believe I got to be involved with that record.

‘I know you’re all here because of how much you love Amy and her music, and we’re so honoured to be a part of that, celebrating her with you tonight.’

One source at the concert said Ronson appeared ‘visibly moved’ by the occasion as he smiled and clapped along from the side of the stage.

They added: ‘Mark was clearly emotional. He was smiling throughout, but you could see that the significance of being back in Camden with Amy’s band was not lost on him.

‘There was a real sense that Amy was present in the room through the music. For Mark, it was a chance to celebrate what they made together and recognise just how much it still means to people.’

The venue was especially fitting because it was where Winehouse made her final public appearance on stage, joining her goddaughter Dionne Bromfield just three days before her death in July 2011, aged 27.

Outside, fans had lined the street wearing Winehouse-inspired winged eyeliner, leopard print and towering beehives, while cigarette smoke hung in the air.

Inside, the Roundhouse had been transformed with red velvet curtains and fringed lampshades in a nod to the late singer’s distinctive retro style.

The Amy Winehouse Band performed Back To Black in full, with guest singers taking on its 11 tracks.

Corinne Bailey Rae sang the title track, while Jorja Smith performed Some Unholy War and rising star Skye Newman took on Addicted.

Ronson later played guitar before the performers joined him on stage for the finale, a rendition of Valerie – the Zutons song which Winehouse and Ronson turned into a hit in 2007.

The concert will be broadcast on BBC Two and BBC iPlayer on Saturday at 9.35pm.

It will also air on BBC Radio 2 and BBC Sounds during Jo Whiley’s show on Monday from 7pm.
