And there was me keyword searching away, stumbling across your post and hoping that you had it!

Ah well...

*scrabbles about frantically under desk* there's a dusty old cassette with it on down here somewhere!

However, in the unlikely event that you still care, I can furnish you with most of the first verse from memory:

Is this the Royal life?
Is this publicity?
On Panorama or on ITV with Dimbleby
It's no suprise
The blame is all Di's you see
He's just a poor boy
He needs your sympathy
Because he's sitting here, all alone
First in line to the throne
