Have you ever done this?

See what song was #1 on the day you were born. (You might have a Beatles song or solo).

My number #1's are:
'You're So Vain' by Carly Simon in the US
'Long Haired Lover From Liverpool' by Little Jimmy Osmond in the UK
'Ben' by Michael Jackson in Australia

See which songs you get
