Coldplay dedicated its slow tempo tune "Fix You" to Mick Jagger at a concert in New York City.
Chris Martin told the crowd Monday before singing the encouraging song about recovering, "It's for Mick Jagger."
Jagger's longtime girlfriend, fashion designer L'Wren Scott, committed suicide in March.
A memorial was held in New York last week. Jagger sang Bob Dylan's "Just Like a Woman" at a celebrity-filled memorial service. Actresses Sarah Jessica Parker and Ellen Barkin were among the guests in attendance.
Martin doesn't quite have Jagger's moves, but the singer danced wildly onstage with his arms swinging as he sang tunes from the band's catalog, including songs from their new album "Ghost Stories," out May 19.
He played the piano and guitar throughout the hour-long set at the Beacon Theatre, performing well-known hits like "Speed of Sound," "Clocks," and "Viva la Vida" as colorful laser lights beamed and white stars hung from the ceiling above the stage. Confetti burst from the sides of the stage after they performed the dance-flavored tunes "Every Teardrop Is a Waterfall" and "A Sky Full of Stars."
Martin and Gwyneth Paltrow, who married in 2003, announced they were separating in March. While singing the song "Magic" -- which features lyrics like "No I don't ... want anybody else than you" -- one girl yelled: "Hang in there, Chris!"
The British foursome closed the show with "True Love," which Martin asked the crowd not to film and post on YouTube.
"(This) is the best song off our new album that no one has ever heard yet," he said. "Sometimes you have to keep these things to yourself."
He made a heart symbol with his hands after performing the tune, which included the lyrics, "Once upon a time I was yours, you were mine."
"Ghost Stories," the Grammy-winning group's sixth album, features production work from Paul Epworth, best known for producing and co-writing "Rolling In the Deep" and other tracks on Adele's colossal "21" album.
