π - Coldplay lyrics

(Verse)
I found a number i didn't know that it was a number
Because it looked like a symbol to me
I put it on my paper and i handed it to the teacher
I said it's a number and he said yes and it starts with three
It's a number that goes on forever
It's a number only conceptually

(Chorus)
3.14 other stuff comes after
But basically it's a little more than three
Three
Three
