Music News:  Green Day for The Simpsons

It's set to be one of the biggest movies of 2007 (like there could be any more in 2007, with news seaping through that Pirates of the Caribbean: At World's End has broken box office records yet again - pulling in over $400 million in it's first six days) but The Simpsons Movie is about to get a little bigger.

Reports have been leaked on the highly guarded flick, that rockers Green Day have made their own rendition of the infamous Simpsons theme song for the movie which is set to hit theatres world-wide on July 27.

As part of the marketing plan, Warner Bros. Records (Warner Music Australia) are set to release the song as a single on July 24 (just three days prior to the flicks release).

It's also confirmed by Matt Groening, the Simpsons Creator, that Green Day will appear in the film (joining the likes of The Red Hot Chilli Peppers and The Smashing Pumpkins who have previously appeared in the series). Surely some of the world's biggest rock-stars would be slightly miffed at missing out.
