If you know diddly-squat about Bo Diddley, now’s a good time to find out. Diddley, who died June 2 at 79, was one of the founders of rock and roll who, like Chuck Berry and Little Richard, felt slighted that he didn’t get more recognition – and more money — for the music that Elvis Presley popularized. Like James Brown, Diddley was one of the hardest working men in show business. He toured almost to the very end, giving it his all. I saw one of his last concerts, October 7, 2006 at the Paramount Theatre in Austin, Texas. Though diabetes and old age had taken its toll and rendered him unable to perform except while seated in a chair, he gave an energetic, sexy performance and elicited squeals from women in the audience when he sang his hit “I’m a Man” with full-blooded, bravado. He was inducted into the Rock ‘n’ Roll Hall of Fame in 1987. Hear Bo play “Bo Diddley,” the song with the syncopated rhythm he was known for, in this clip from his debut on The Ed Sullivan Show in 1955. One of the best collections of his work is 20th Century Masters the Millennium Collection: Best of Bo Diddley ($9), which includes remixes of original recordings of “Bo Diddley,” “Who Do You Love” and “Road Runner.” For those who already know Bo, this amazing CD ($23) has various versions, alternate takes and mixes (scroll down on the site to hear snippets) of many of his early recordings for the legendary Chess label, including “Diddy Wah Diddy.” See the man behind “I’m a Man” in Bo Diddley and the All Star Jam DVD ($11.49), which includes Bo and friends Ron Wood, Mick Fleetwood and Mitch Mitchell (of the Jimi Hendrix Experience) at a concert filmed live at the Irvine Meadows Amphitheatre in 1985.
