song in which he fully found his sound. B.B. King credits Walker as inspiring him to take up the electric guitar, but his influence extended far beyond the blues to jazz and rock and roll. Among other innovations, "Mean Old World" has a two-string guitar lick where Walker bends notes on the G string up to the notes on the B string, which would be used by Chuck Berry in "Johnny B. Goode" and other songs. "Caldonia" was first recorded by Louis Jordan and then by Erskine Hawkins and others; the Hawkins version was called "right rhythmic rock-and-roll music" by Billboard. (The actual concept of rock and roll had not actually been defined at that time.) Several sources indicate that Little Richard was influenced by Louis Jordan. In fact, the artist said Caldonia was the first non-gospel song he learned; and the shriek on the Jordan record "sounds eerily like the vocal tone Little Richard would adopt" in addition to the "Jordan-style pencil-thin moustache". "Rock Me Mamma" by Arthur "Big Boy" Crudup, recorded on December 15, 1944, was the blues singer's first and biggest R&B chart hit, but in later decades became overshadowed by his – at the time, much less successful – 1946 recording of "That's All Right". "Strange Things Happening Every Day" by Sister Rosetta Tharpe, recorded in 1944 with pianist Sammy Price, was a boogie-woogie flavored gospel song that "crossed over" to become a hit on the "race records" chart, the first gospel recording to do so. It featured Tharpe on an electric guitar and is considered an important precursor to rock and roll. A National Public Radio article commented that "Rock 'n' roll was bred between the church and the nightclubs in the soul of a queer black woman in the 1940s named Sister Rosetta Tharpe". "The Honeydripper" by Joe Liggins, recorded on April 20, 1945, synthesized boogie-woogie piano, jazz, and the riff from the folk chestnut "Shortnin' Bread", into an exciting dance performance that topped the R&B "race" charts for 18 weeks (a record later shared with Jordan's "Choo Choo Ch'Boogie") and also made the pop charts. The lyrics proclaimed urban arrogance and were sexually suggestive – "He's a solid gold cat, the honeydripper... he's a killer, a Harlem diller...". "Guitar Boogie" by Arthur Smith, originally recorded in 1945 but not a hit until reissued in 1948, was the first boogie woogie played on the
