You're not going to believe this. Bill Haley's "Rock Around The Clock". I bought it new as a little boy and still have it.
This was about forty years before CD's were invented.
Next important was Elvis--a four-song extended record with Paralyzed, Love Me, Blue Moon Of Kentucky and . . .I forgot what the other song was. I'm getting senile along with sentimental. See what you did.
