EXTREMELY late Pi Day project. I wanted to make a Pi Day project around March but it failed. The song contains about 200 digits. Pi is the ratio of a circle's circumference over it's diameter, and it has a lot to do with circles (and it is the Greek letter P as well.)
The Pi song is from Youtube. When I was younger I memorized it. I did not make the pie joke up: it's been around for years. Trivia: The Pi Song is played at 92 BPM. (I'm probably gonna attract all the math geeks next year with this project and the sequel to my game PiHep if that is shared.)
