Road Runner, the second volume of Hip-O Select's ongoing chronicle of Bo Diddley's complete Chess/Checker master recordings, covers roughly one calendar year whereas its predecessor, I'm a Man, spanned four — a good indication that 1959 was an eventful year for Bo. During this one year, he had his biggest pop hit in the jive-talking "Say Man" and had another sizable R&B hit with "Crackin' Up," but both these sides were cut in 1958 and released as a single in 1959.
