true fusion of 3–2 clave and R&B/rock 'n' roll. Bo Diddley has given different accounts of the riff's origins. Sublette asserts: "In the context of the time, and especially those maracas [heard on the record], 'Bo Diddley' has to be understood as a Latin-tinged record. A rejected cut recorded at the same session was titled only 'Rhumba' on the track sheets." Johnny Otis's "Willie and the Hand Jive" (1958) is another example of this successful blend of 3–2 claves and R&B. Otis used the Cuban instruments claves and maracas on the song. Afro-Cuban music was the conduit by which African American music was "re-Africanized", through the adoption of two-celled figures like clave and Afro-Cuban instruments like the conga drum, bongos, maracas and claves. According to John Storm Roberts, R&B became the vehicle for the return of Cuban elements into mass popular music. Ahmet Ertegun, producer for Atlantic Records, is reported to have said that "Afro-Cuban rhythms added color and excitement to the basic drive of R&B." As Ned Sublette points out though: "By the 1960s, with Cuba the object of a United States embargo that still remains in effect today, the island nation had been forgotten as a source of music. By the time people began to talk about rock and roll as having a history, Cuban music had vanished from North American consciousness." Early to mid-1950s At first, only African Americans were buying R&B discs. According to Jerry Wexler of Atlantic Records, sales were localized in African-American markets; there were no white sales or white radio play. During the early 1950s, more white teenagers started to become aware of R&B and began purchasing the music. For example, 40% of 1952 sales at Dolphin's of Hollywood record shop, located in an African-American area of Los Angeles, were to whites. Eventually, white teens across the country turned their musical taste toward rhythm and blues. Johnny Otis, who had signed with the Newark, New Jersey-based Savoy Records, produced many R&B hits in 1951, including "Double Crossing Blues", "Mistrustin' Blues" and "Cupid's Boogie", all of which hit number one that year. Otis scored ten top ten hits that year. Other hits include "Gee Baby", "Mambo Boogie" and "All Nite Long". The Clovers, a quintet consisting of a vocal quartet with accompanying guitarist, sang a distinctive-sounding combination of blues and gospel, had the number five hit of the year with "Don't You Know I
