"Say Man" was Bo Diddley's one and only Top 40 pop hit, which seems pretty surprising when you consider the man's body of work -- while such obvious classics as "Bo Diddley," "I'm a Man," "Who Do You Love," "Mona," and "You Can't Judge a Book By Its Cover" never crossed over from the R&B charts, "Say Man," which sounds like a time-filling comedy routine by comparison, was the number that was embraced by pop radio and the single-buying masses. Go figure. But if "Say Man" is filler, it's sublime filler -- here Bo and Jerome Green (Bo's maracas player, and let's pause to mention no other artist would be so obsessed with rhythm and such a visionary that they would hire a guy just to play maracas) exchange comic insults for two and a half minutes in a cleaned-up version of a couple guys running the dozens. However, most guys ranking out on each other wouldn't have a backing track this good, an up-tempo shuffle that all but demands movement, and as it turns out Bo and Jerome were a great comedy team, with Jerome playing the clown with his wild laugh and exaggerated drawl ("You so ugly, the stork that brought you into the world oughta be arrested!"), while Bo stays cool as the unflappable tough guy, no matter how crazed his banter may be ("You that thing I throw peanuts at!"). In the grand tradition of Otis Redding and Carla Thomas's "Tramp," "Say Man" sounds like a bit of comic stage business that somehow made it into the recording studio, but like "Tramp" it happens to be pretty funny, and the music cooks -- though someone ought to tell Bo that Texas does not count as South America, even if I lack the courage to do it myself.
