Released publicly (and legally) for the first time, here’s the 1973 recording by “the best live band in the world” (according to Billboard) made at this Denver club, which was set up to look like the ballpark inside. The band was at their pinnacle of fame and peak of their powers then; behold on CD or vinyl: “Smoke That Cigarette,” “Good Rockin’,” “Truck Drivin’ Man,” “Down and Out,” “Lawdy Miss Clawdy,” “Mama Hated Diesels,” “Sally Walker” and more! Rock Beat.
