Green Day have unveiled a tribute to late singer Amy Winehouse. The American Idiot rockers debuted the new track - which makes references to the "Rehab" hitmaker's troubled life up to her unexpected death on July 23 - at a secret show at the Tiki Bar in Costa Mesa, California, on Thursday.

According to lyrics posted on the band's official website, the opening lines are, "Amy, is your heart singing out of tune/ Are your eyes just singing the blues/ Dirty records from another time/ Some blood stains on your shoes."

The final part of the track laments Amy's premature death at the age of 27, as well as the drug and alcohol addictions which had plagued the star throughout since 2006: "You're too young for the golden age/ 'Cause the record bin's been replaced/ 27 gone without a trace/ And you walked away from your drink."

Green Day are the latest artists to pay tribute to Amy Winehouse, after U2, M.I.A., Coldplay and Dionne Bromfield have all dedicated tracks or dedicated parts of their live shows to the star.
