They're both iconic musicians in their own right, but did you know that Prince and Paul McCartney were also pals?
In fact, their friendship was even solid enough for the latter to write to the former for a helping hand when it came to money.
McCartney once asked Prince for a donation to help establish the Liverpool Institute of Performing Arts, which he co-founded in 1996, and the opening line is the most Macca-esque opening line ever, as you'll see below.
He also suggested that Prince might stop by the Institute to 'teach some moves'.
The handwritten letter was auctioned in Boston over the weekend and sold for $14,822.
Read the full text and see the letter below:
"Dear Princely person,
Hi there! I know how hard it is to always be getting letters that ask for some favour or another, so it was not easy for me to accept the job of Lead Patron for a Performing Arts School to be located in my home town, Liverpool.
But, you guessed it! I did agree to do it, so now I'm writing to "friends and all good people" to try and interest them in the scheme.
The story started just after the inner-city riots in Liverpool a few years ago. A friend suggested that "what the city needs is a "Fame" School."
I liked the idea as a possible positive focus for local and overseas kids, but it was only later when I went back to my own old school that was in ruins, that I thought by locating a Performing Arts Centre there we could save the 1825 building in the process.
So..... (phew!)
We're now well on our way, as the enclosed info shows, but there's still a lot to be done.
Now the hard part. A donation from you would be a great boost to the project, and I know your involvement in some way, would be a thrill for everyone concerned.
Hope you didn't mind me writing this, it's so long since I've written letters I feel like I'm back at school myself.
Anyway, one of these days you'll have to come and teach a class some moves!!
Who knows, it may turn out to be something special for thousands of future kids.
Thanks for looking at this.
Cheers, & love
Paul (McCartney)"
