Noel Gallagher has had a dig at Green Day, claiming that 'Boulevard Of Broken Dreams' is a rip off of 'Wonderwall'. Here are the words he used: "If you listen, you'll find it is exactly the same arrangement as Wonderwall. They should have the decency to wait until I am dead [before stealing my songs]. I, at least, pay the people I steal from that courtesy. They consider themselves to be - and I quote - 'a kick-ass rock 'n' roll band'. They could not be less kick-ass if they tried".
Personally I'd rather listen to Green Day than Oasis on any day of the week (except possibly Tuesdays), though 'Boulevard' does have similarities to 'Wonderwall' - certainly they complement each other very well when mashed together, as you can hear for yourself if you get a copy of that fabulous albeit slightly illegal Green Day mash up album 'American Edit' (which you may or may not be able to preview at http://www.myspace.com/americanedit)
