The day after attending his friend and musical foil Amy Winehouse's funeral, producer/band leader Mark Ronson paid tribute to the fallen star at a concert on Wednesday night.

According to NME.com, Ronson brought Zutons singer Dave McCabe onstage to play his band's song "Valerie," which was famously recorded by Winehouse on Ronson's 2007 Versions covers album. Ronson, who produced the two most well-known tracks on Winehouse's 2006 breakthrough Back to Black album, "Rehab" and "You Know I'm No Good," dedicated "Valerie" to his troubled muse.

"It's really lovely getting to play some music here for you tonight. That's what makes everything better," he told the crowd at the Old Royal Naval College in Greenwich, England. "I went to her service yesterday and there was a rabbi that spoke and he said that somebody's life is measured in deeds and not years and that's the best thing I heard yesterday. ... The genius in that woman and what she shared with us is pretty special. I'm not going to get all morbid on you. It's just nice to be playing music to people who like good music. She is my sister, wherever she is."

In addition to the version of "Valerie," Ronson invited members of Winehouse's backing band onto the stage at one point for another run through "Valerie," as well as Rumble Strips singer Charlie Waller, who sang a cover of "Back to Black." Ronson also played "Rehab" during a short DJ set in the middle of the show.

Winehouse was found dead in her Camden apartment on Saturday at the age of 27. Initial autopsy results were inconclusive and additional toxicology tests are expected to take two to four weeks.

Also on Wednesday, "The Voice" coach and "Forget You" singer Cee Lo Green revealed that despite reports earlier this year that he had recorded a duet with Winehouse for her next album, the two had never actually hooked up. Green told E! News the pair were trying to get together in the studio but never made it happen. "We were discussing working together ... we have a mutual friend, Salaam Remi," he said of the producer who worked on several tracks on Back to Black.

"There was a rumor that we had already recorded together. It wasn't true and I don't know where that came from. But we did grow fond of each other and thought we could work together. ... I could listen to her and she registered to me as the real thing. ... It's so untimely and unfortunate. What a loss. Music has lost a daughter."
