What's an old song you'll never get tired of?

Oldies but goodies, what's an "old" song you really like? How far back do you remember a good song? Post it please. Here's mine. There was another one that I couldn't post as it wouldn't show here, called Red Rubber Ball, by Cyrkle. I hope this one is ok.
