I recently saw Max Weinberg's Big Band and it was a real treat to hear them play the theme from M Squad - especially since I had just watched all the episodes of the series over the past year or so. Lee Marvin was one cool cucumber of an actor who wore a cool hat during the series run. It's great to see him walk the streets of Chicago in his relentless pursuit of criminal apprehension. Like Joe Friday, we never really see Marvin's Frank Ballinger off the clock, but unlike Friday it seems like when he does get the occasional day off, Ballinger might actually have a good time at a local windy city watering hole. I watched many of the episodes in the wee hours of the night, which was the perfect time to enter Frank's black and white universe of no nonsense crime fighting.
