on October 3, 1942, he described Count Basie's "It's Sand, Man!" as "an instrumental screamer.. [which].. displays its rock and roll capacities when tackling the righteous rhythms." In the April 25, 1945 edition, Orodenker described Erskine Hawkins' version of "Caldonia" as "right rhythmic rock and roll music", a phrase precisely repeated in his 1946 review of "Sugar Lump" by Joe Liggins. A double meaning came to popular awareness in 1947 in blues artist Roy Brown's song "Good Rocking Tonight", one of the contenders for the first rock'n'roll record. It was covered in 1948 by Wynonie Harris in a wilder version, in which "rocking" was ostensibly about dancing but was in fact a thinly veiled allusion to sex. Such double-entendres were well established in blues music but were new to the radio airwaves. After the success of "Good Rocking Tonight", many other R&B artists used similar titles through the late 1940s. At least two different songs with the title "Rock and Roll" were recorded in the late 1940s: by Paul Bascomb in 1947 and Wild Bill Moore in 1948. In May 1948, Savoy Records advertised "Robbie-Dobey Boogie" by Brownie McGhee with the tagline "It jumps, it's made, it rocks, it rolls." Another record where the phrase was repeated throughout the song was "Rock and Roll Blues", recorded in 1949 by Erline "Rock and Roll" Harris. These songs were generally classed as "race music" or, from the late 1940s, "rhythm and blues", and were barely known by mainstream white audiences. However, in 1951, Cleveland disc jockey Alan Freed began broadcasting rhythm, blues, and country music for a multi-racial audience. As one source points out, there was some controversy in his selection of recordings: "Freed would play the original singles by the black artists instead of waiting for a white singer to cover them". Freed, familiar with the music of earlier decades, used the phrase 'rock and roll' to describe the music he aired over station WJW (850 AM); its use is also credited to Freed's sponsor, record store owner Leo Mintz, who encouraged Freed to play the music on the radio. Several sources suggest that Freed discovered the term (a euphemism for sexual intercourse) on the record "Sixty Minute Man" by Billy Ward and his Dominoes. The lyrics include the line, "I rock 'em, roll 'em all night long". Freed did not acknowledge the suggestion about that source (or the original meaning
