Just saw the Penny Lane video and noticed that when they were riding the horses that George was the one riding a dark horse! Do ya think?!
"While the term "dark horse" usually refers to an unlikely or surprise winner,Harrison states in I, Me, Mine that he was unaware of that meaning at the time;his lyrics instead referred to someone who carried out clandestine sexual relationships − that is, a dark horse in Liverpudlian terms."
WikipediaWho knows? LOL
