youcan find out which number one song was on your birthday. Now, I wasn't born in 1966, but if I was, it would have been "Paperback Writer" by the Beatles, which is not only an awesome song, but is now in my head and will be for the rest of the night, for sure. Unf, i was born in 1981, so it's some medley. So, I'll take 1966.
