It has to be one of those getting older things that causes you to have these earth-shattering realizations about the passage of time that seem difficult to believe.
In 1950, Ella Fitzgerald released the LP Pure Ella which featured this song.
Just 15 years later, the Beatles released the Rubber Soul album. (I was only 5 years old and they had already released 5 previous albums!)
A scant 15 years later, the Police released their third album, Zenyatta Mondatta. Incidentally, this was also the year John Lennon was murdered.
And now that was 30 years ago.
