Unfortunately I don't think there's any way of contacting John Lydon (unless you're a mate, and you have his phone number, etc). The email info on his
website basically gives potential correspondents the brush-off.
If this is someone else using the PiL logo for their own business, I'd say there's a clear trademark infringement there. I'm sure John would gleefully haul them through every court in the land, cackling outrageously all the while.
But that's exactly the reason I don't think it is someone else. A competent and well-funded property development company (as FiL must surely be, because you don't bankroll apartment projects in a hot spot like Kingston without knowing what you're doing, and without having a big wedge of cash to hand) wouldn't expose itself to that kind of obvious legal own goal.
The only reason FiL are using the PiL logo is because they're
allowed - and that's got to mean John's involved. But I don't think it's possible to squeeze a confirmation out of the man himself.
I suppose the one sure way of proving this would be to fork out a fee for the company info, as
zotz mentioned above. If John's a director, his name will be listed. Then again, he might be involved without actually being a director, in which case I'd have paid up for nothing.
Maybe the best option is to bung an email in the direction of the
Fodderstompf website (from which I nicked the small PiL logo in my main post, he says, hastily dishing up credit). Maybe they'll know about John the property tycoon, maybe they won't. Either way, I'm sure they'd be interested in the sudden outbreak of PiL logos all over the west London hinterland...
