Evidently Those In The Know have been aware of this track for ages but since I am clearly Not In The Know I am afraid that it has only just come to my attention - and then only thanks to my good friend Dr. Al.
I find it a hoot - and strangely life-affirming.
According to Wiki there's a little Aerosmith via Eminem in the 'mash' too, aside from the obvious Travis/Oasis/Green Day. Always like a grating of nutmeg myself.

[Lots more of this sort of thing to download at Party Ben's site, where he also reveals that he used the Eminem because he didn't have any actual Aerosmith and couldn't get any off iTunes. Bless].
