From soundgenerator.com:-
Busted defy 'boy band' status with their latest release. Imagine a luke warm Blink 182 and a slice of OPM. That's the US influence on the young lads now holed up in deepest Finchley, North London. Very commercial and bound to hit the top 5. Mind you I didn't know they had American accents up there. Still they haven't lost their guitar-based sound and are determined to have a bit of fun at the same time. Check out the version of the Beach Boys' wonderful 'Fun Fun Fun'. The fact that their parents weren't even born when it first came out is...well... pretty irrelevant.
The DIEJ re-mix (track 4) actually is better than the single version. Nice and tuff. Lots of bleeps and nice tuff guitar.
It’s going to please die hard Busted fans and may well pick up quite a few more on the way.
