What links these people?

I found that George Michael bought John Lennon's old piano at an auction but I can't link it to Mr. Burns....

My first thought was their middle names were all last names. But I can't confirm Kyriacos.

John Wilson Lennon (He later changed it to John Ono Lennon)
C. Montgomery Burns
Georgios Kyriacos Panayiotou (George Michael)

They all changed their names? Not a big enough fan of the Simpsons to answer that one.

I found this list of Beatle references in The Simpsons: http://www.snpp.com/guides/beatles.refs.html

Maybe someone can connect them up.

John's middle name was WINSTON parados It's the Mr Burns that has me stumped.
