Sunday Side Up Easter Egg: "Got My Mind Set on You" by George HarrisonJohn Lockwood
Before Beatlemania became a thing... five months before the Fab Four appeared on The Ed Sullivan Show in 1963... George Harrison traveled to the United States to see his sister in the countryside of Illinois. While there, he freely visited record shops and bought many albums, one of which contained a song written by Rudy Clark and originally recorded by James Ray called...?
"I've Got My Mind Set on You"!
In 1987, with the help of some good friends including (ELO leader and producer extraordinaire) Jeff Lynne, George released "Got My Mind Set on You" as a single from his Cloud Nine album... which went to #1!
Fun Fact: As the Beatles wrote and gave away their songs to others to perform and release as singles, this is the rare occurrence of a solo Beatle covering someone else's song (aka "Easter Egg")!
There are two versions of the video for George's take on "Got My Mind Set on You". The first takes place in an arcade... and the second, a more Monty Python-esque version, is my personal favorite!
