#1 Song On Your Birthday?

At The Slice blog, SR colleague Paul Turner posted a link that caught my interest. It shows you the No. 1 song on your birthday. I followed the Top 40 as a kid in the 1960s. So I enjoy knowing what chart toppers are on a specific day, including the No. 1 song on my birthday, Nov. 20, 1949, which happened to be Frankie Laine’s “That Lucky Old Sun.” I’ve heard of Frankie Laine (“Rawhide,” “Mule Train,” etc.), of course. But I’ve never heard of “That Old Lucky Sun.”

Question: What was the No. 1 song on your birthday?
