I lived in the apartment above the Nitty Gritty in 1971-72 as I was completing an English degree. I just want to lend my voice to those who remember Marsh fondly.
It's important to note - and though a few have touched on it, it seems largely ignored - that March was an important curator and purvey of Chicago blues during this time. His was the top live music club, the the Gritty for a time formed a triangle of sorts, whereby Chicago blues acts ventured north to Madison, then Milwaukee, before going back home. During breaks between sets and after hours, bluesmen often found themselves in our livingroom upstairs - drinking, relaxing, laughing, whatever. I got to know Otis Rush, Hound Dog Taylor, Luther Allison, Buddy Guy, Jimmy Fast Fingers Dawkins, A.C. Reed and many others. Needless to say, it offered me an education that rivalled anything UW had to offer. I ended up being Luther's roadie for awhile. And have Marsh to thank for it all.
He was the greatest guy, hiring three of my friends and fellow students to tend bar, clean up or cook downstairs. And he never mentioned the dozens of times we'd sneak down and spirit away a few Gritty burger patties for late-night snacks.
Marsh was as important to the early-70s resurgence of the blues in the Midwest as anyone, and he should be remembered and honored for that as much as anything.
