New Song, Green Day Collab To Enrich U2 Best-Of
A new song and a cover of Scottish punk band the Skids’ “The Saints Are Coming” with Green Day will be found on a U2 compilation due Nov. 21 via Interscope. The as-yet-untitled set, which will also be available in a deluxe edition, will feature “16 of U2’s best-songs,” according to the band’s Web site.
Both the new song and the Skids cover were recorded last month at London’s Abbey Road Studio with producer Rick Rubin. U2 and Green Day debuted the cover live last week at the re-opening of the New Orleans Superdome; it is available for download exclusively until Oct. 30 via Rhapsody, after which point it will hit additional download retailers. A CD single will follow on Nov. 6.
U2’s most recent compilation, “The Best Of 1990-2000,” was released in December 2002 and included material up through the 2000 album “All That You Can’t Leave Behind.”
As previously reported, the band will resume its Vertigo tour Nov. 7 in Brisbane.
