"Mona (I Need You Baby)" is a song written by Ellas McDaniel (Bo Diddley) that appeared as the B-side to his 1957 single "Hey! Bo Diddley". According to Diddley's obituary in The New York Times, "Mona" was a song of praise he wrote for a 45-year-old exotic dancer who worked at the Flame Show Bar in Detroit. The song also became the template for the Crickets's "Not Fade Away".[1]
