In my previous post about Voyager, I mentioned a golden record containing various sound samples. When discussing this with my friends at work, I mentioned to them that no Beatles music was included, which seemed like an odd omission.
Yesterday I found out that Carl Sagan did in fact want to include a Beatles song, but didn't in the end due to copyright complications. Guess what song he wanted to include? The answer is hilarious: "Here comes the Sun"!
