Back in the late 1980's I was getting dressed to go to work one morning with the local oldies station playing in the kitchen. I heard them say they were going to have a contest and the first caller to know the answer would win a prize. So, I was listening for the contest but had no intention to try to win. I only wanted to see if I knew the answer. So the question came on & they asked, "what was Chuck Berry's only song to reach #1 on the Billboard Pop Charts?" Right away I said to myself "My Ding-A-Ling". People started phoning in and guessing all the major Chuck Berry songs from the 50's and 60's but no one was getting it right. Finally I decided to call. My prize was the 3 CD Chuck Berry Chess Box set. We must have a lot of dumb people living in this part of Pennsylvania because I thought that was common knowledge. God Bless Chuck Berry.
