Mark Ronson led hundreds of people in a singalong of Amy Winehouse's greatest hits as he paid tribute to the star, calling her his "sister", in an emotional live show.

The DJ and music producer, a long-time collaborator with Winehouse and a close friend of the late singer-songwriter, turned a gig to promote his band The Business International into an unofficial memorial concert in Greenwich last night.

His show at the Old Royal Naval College was organised months ago, but he tore up the programme and dedicated the performance to Winehouse, 27, who died at her home in Camden in Saturday.

Ronson, 35, who attended her funeral in north London on Tuesday, told his audience: "I know she's my sister, wherever she is. If you love Amy Winehouse and her music, clap your hands."

The rabbi at the funeral said "somebody's life is measured by their deeds not by their years", Ronson told fans. "And that was the best thing that I heard."

He went on: "She made brilliant music - more than I will make in my entire life. The genius of that woman and what she shared with us is pretty f**king special."

He opened with an acoustic duet of the huge Winehouse hit, Valerie, with Dave McCabe, who wrote it. He finished his DJ set with Winehouse's Rehab and was joined by Charlie Walker from The Rumble Strips to cover Back To Black. For the finale, Winehouse's former backing singers Zalon Thompson and Ade Omotayo, her bass player Dale Davis and drummer Troy Miller joined Ronson to perform Valerie again, with the audience taking lead vocals.

Thanking the crowd, Ronson told them: "You turned what could have been a s**t, morbid Wednesday into a wonderful evening for us."

Urging them to sing "as loud as you can", he said: "Amy, this is for you."

Dressed all in black, Ronson, who co-produced Amy Winehouse's Grammy-winning album, Back To Black, sloped onstage intent on playing her music in tribute.

But this would have been a good gig in its own right, had he not done so.

He covered Valerie with Dave McCabe and when Winehouse's voice on Rehab washed over us during the DJ set, it seemed I'd something in my eye.

Ronson's own output, including the reggae-infused Animal and the anthemic Somebody To Love Me, both featuring Andrew Wyatt's fabulous falsetto, were rapturously received. But inevitably, the Winehouse moments will be remembered. The Rumble Strips gave their guitar-heavy take on Back To Black. And her old backing band took the stage for a tremendously moving version of Valerie.

As the crowd bellowed back the words, it was a reminder that while Winehouse may no longer be with us, her music will live on. For that, we can be grateful.
