Mr. Acker Bilk (someone once said that "Acker" means Mister, making his name from the dept. of redundancy dept.)
Jerry Bilik was a student at the University of Michigan, and eventually a theory and arranging teacher there. After some years there, he ran away to the circus—Ringling Bros.-Barnum & Bailey, to be exact. True story. He was one of my teachers. He's in his late 70s now.
