I came across this and snagged it from callme_al01
What was the #1 song the day you were born?
Google the date and #1 song and then post your #1 song on your LJ - preferably with a Youtube vid if you can find one!
I found this sight which was very helpful, you can enter the date and year choose US or UK then just hit search.
US (I'm sure my mom would love this, her favorite singer. Oh and I saw him in concert when I was about 4 years old)
