I just listened to Jimmy Dale Gilmore's version of I'm So Lonesome I Could Cry. I thought that is so perfect that nobody ever had to record it again. Mack the Knife has probably been done by hundreds of singers. Originally written in German, Macheath has been around a while, from The Beggars Opera to The Three Penny Opera, then on to Bobby Darwin and that awful Louis Armstrong version. There is a tendency to do it finger-popping ala Bobby Darin. His is a really strange juxtaposition of style versus lyrics. Jimmy Dale didn't do that. He drags it. Now we have his dark, haunting version from the French crime film Un Prophete. One more song that doesn't need to be re-recorded. Finally after 90 years, perfection.
