What do you know about I Bake For Jake?

I have no idea what the origin of this bagel factory label is, but I do know who Jake is.  Jake played a stringed instrument on the streets of Ann Arbor in the early 1970's when I was a student at Michigan.  Everyone knew Jake.  We'd wave.  He'd play.  Jake wore distinct dress.  Jake played distinct music.  I'll leave it to others who worked at the Bagel Factory or knew Jake to fill in the blanks.
