There is, so they say, a fine line between genius and madness.

This is obviously a load of old bollocks.

Don’t believe me?

Well, you have to look no further to see just how vast the chasm is that separates these two noggin states, then these two songs: Eleanor Rigby and The Frog Chorus.

Yes, poor old former genius, Paul McCartney went a little bit mad in the 80’s and has seemingly been on a slippery downward slope ever since.

But that hasn’t stopped us from loving the old duffer - even as he stumbles from one disappointing musical release to another embarrassing court appearance - even as his face slowly turns into that of Droopy.

And this is the face that the British Paralympic Fund have chosen to front their fund raising campaign - promoting their athletes as “super heroes”.

Which makes Sir Paul seem like an odd choice.

You see, Paul McCartney’s recent track record when it comes to judging the characters of disabled people has been, let’s be honest, poor at best.

The last disabled women who he thought was “pretty amazing” turned out to be a screeching, one-legged, former porn-star, crack-pot who cost him £24 million to get rid of.

Good one, Paul.

So when you ask him to front your campaign praising the high quality characters of some disabled women (OK and men), it’s a little like asking the Captain of the Titanic to endorse your brand of binoculars.

Sir Paul tells us that for just £3 a month we can help the Paralympic team’s pursuit of gold medals at the London 2012 games. This, coincidentally, is how Paul McCartney is paying his divorce settlement - in monthly £3 payments.

He’s only got 7,999,984 more payments to make and he will finally be free of Geordie maniac. Aren’t direct debits brilliant?

Anyway, when it comes to advice, if Sir Paul offers to give you some song-writing tips, get your pen and paper out. If he offers to find you a wife, run a mile.

And if you can do that in under 4 minutes, he might be able to get you some funding too.
