Few records can match the raw exuberance of the Baby Face Leroy Trio’s two-part “Rollin’ and Tumblin’” on Parkway, a small and short–lived Chicago label. Muddy Waters and Little Walter join singer-drummer Leroy Foster on this rambunctious 1950 rendition of an old Hambone Willie Newbern tune. Part 2 has no verses at all—just a mélange of the trio’s moans, hums and yelps. When Leonard Chess heard the record, he had Muddy cut his own two-part version on Aristocrat, the label that preceded Chess Records. Muddy added more verses and delivered the goods but his record not did have the wild abandon of the original. When Little Walter’s fame later rocketed as a solo artist, the Herald label reissued Part 2 of the Parkway single as a Little Walter record, “Rollin’ Blues.”
