Musicians Tre Cool, Billie Joe Armstrong and Mike Dirnt of Green Day pose for a portrait at the 2009 American Music Awards at Nokia Theatre L.A. Live on November 22, 2009 in Los Angeles, California.

Along with playing a slew of previously unheard tracks, Green Day honored the late Amy Winehouse by debuting a new song, "Amy," at their "secret" show in Costa Mesa, Calif., last Thursday (Aug. 11). Three days later, the band posted the full lyrics to the song on its official website.

"Amy don't you go/I want you around/Singin' woah, please don't go/Do you wanna be a friend of mine?" pleads frontman Billie Joe Armstrong on the chorus of the song, which he performed without bandmates Mike Dirnt and Tre Cool. The track ends with Armstrong singing, "May I have this last dance/By chance if we should meet?/Can you write me a lullaby?/So we can sing you to sleep."

"Amy" was part of a one-off Green Day gig at Costa Mesa's Tiki Bar in which all benefits went to the Cystic Fibrosis Foundation. The pop-punk veterans -- whose most recent full-length, "21st Century Breakdown," was released in 2009 -- played a full set of new material, with tracks like "Nuclear Family," "Carpe Diem" and "Sweet 16" followed by an encore of classic Green Day tracks like "Minority" and "Burnout."

"Thanks everyone for coming out to the show Thursday night and supporting us and the Cystic Fibrosis Foundation," the band posted on its website. "We have been in jamming and writing new songs for the last few months. It felt great to play these new Green Day songs live and share our 'work in progress'.. Stay tuned for more!"
