I can't help it. Watching a Southampton-based Green Day tribute act attempt an American accent peppered with "f**k yeah"s makes the mind wander.

Does our Billie Joe Armstrong impersonator and frontman Biscuit Jay continue that accent offstage, I wonder.

Does he get more groupies because he tilts his head like the real Green Day star and, if so, does he maintain the accent and the f**k yeahs when he's on the job?

Am I the only person here thinking these things, as the band rip into opener American Idiot?

Greenish Day are no ordinary tribute act. Biscuit Jay fronts punk band Kristina and he used to head up Blink 182 tribute act, Stink 182, until the Californian punkers split up.

So here he is, riding the coat-tails of Green Day's stunning album American Idiot.

Boulevard Of Broken Dreams, Basket Case and St Jimmy are just like the real thing (if you ignore the Southampton twinge).

There's a part in every Green Day show where the band invite an audience member up on stage to play guitar. At the end of the song, the lucky kid gets to keep the guitar.

Greenish Day have a similar line in audience participation, though inviting onstage a drummer, guitarist and bassist only serves to point out that no one will be getting a free guitar.

It's still the highlight of the gig: three Green Day fans passably impersonating a tribute act of the band they love. For one night only they can become, to their friends at least, Jesus Of Suburbia.
