Green Day has released the official video for their 'Twilight' soundtrack song 'The Forgotten' which features on final instalment of the book-to-film franchise 'The Twilight Saga: Breaking Dawn'.

It's a romantic piano tune that speaks straight to the heart; coupled with Billie Joe Armstrong's soft but passionate vocals telling a melancholy tale of the two troubled lovers of the movie, it really does serve as the perfect song for the last part of Bella Swan and Edward Cullen's story. The video itself features clips from the movie as well as footage from Green Day's live shows making a great promotional feature for both the 'Twilight' franchise and the band.

The 'American Idiot' rockers have admitted to agreeing to do the soundtrack number because they wanted to be a part of the whole scene. 'We readily agreed because the films are an insane cultural phenomenon, and we have always been impressed with the way the Twilight soundtracks are so carefully curated', said bassist Mike Dirnt talking to Yahoo! Movies.  And it's just as well because GD fans are growing less than impressed with the band after they chose to cancel the rest of their tour dates for this year and the beginning of next year following concerns of Armstrong's well-being after being sent to rehab for alcohol and drug related problems.
