Play.com appears to have inadvertently broken the news on what Green Day songs will feature in its outing on Rock Band.
The posting on the retailer's website claims that albums American Idiot and Dookie will appear in their entirety. In addition, players who bought the DLC of the group's 21 Century Breakdown songs will now be able to complete the collection with the addition of missing songs.
Green Day: Rock Band was announced last December, with front man Billie Joe Armstrong saying: "We've worked with the Rock Band team in the past year to enable our fans to play tracks from 21st Century Breakdown, and we're excited to now be working on a game, spanning our entire career."
"We want people to fire this up, choose their favourite Green Day tracks, and play along with us as Rock Band avatars so they can feel what it's like to perform on stage as Green Day."
