Paul McCartney once wrote a letter to Prince asking for donations to help create the Liverpool Institute for Performing Arts, which the Beatles legend formed in 1996. The same letter recently sold at auction for nearly $15,000.

The two-page, hand-written correspondence was signed “Paul McCartney” and sold at Boston’s RR Auction for $14,822.

“Dear Princely person,” the letter begins. “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.”

McCartney later added, “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!!”

Following Prince’s death in April, McCartney tweeted, “Saddened by Prince’s death. Proud to have seen in the New Year with him. He seemed fine and played brilliantly funky music.” He added in a follow-up, “God bless this creative giant. Thanks Prince. Love X Paul.”
