Number one song in America when . . . .

I borrowed this from Richmond, and depending upon which song was number one on your birthday, you may think that this website is cool. Why did I put it that way? My number one hit was "Bad Blood" by Neil Sadaka. WTH? I've never heard that song before. Does anyone know a website where I can listen to it? And my life song is Boyz II Men "I'll Make Love To You". ?????? That can be taken many different ways.
