electric guitar, and was much imitated by later rock and roll guitarists. The tune was based on "Pinetop's Boogie Woogie" from 1929. "The House of Blue Lights" by Freddie Slack and Ella Mae Morse was recorded on February 12, 1946. The song was co-written by Slack with Don Raye, and, like Raye's "Down the Road a Piece", was recorded later by many rock and roll singers. Morse was one of the first white singers to perform what would now be regarded as rhythm and blues music. "The House of Blue Lights" was an important precursor to rock and roll. "Route 66", was recorded by the Nat Cole Trio on March 15, 1946. Written by Bobby Troup, the song was a big hit for Cole – who by that time already had 11 top ten hits on the R&B chart, starting with "That Ain't Right" in 1942 – and was later widely covered by rock and roll performers, including Chuck Berry. "Boogie Woogie Baby," "Freight Train Boogie" and "Hillbilly Boogie" by the Delmore Brothers, featuring harmonica player Wayne Raney, were typically up-tempo recordings, heavily influenced by the blues, by this highly influential country music duo, who had first recorded in 1931. "Open the Door, Richard" was a novelty R&B record based on a comedy routine performed by Dusty Fletcher, Pigmeat Markham and others. It was first recorded in September 1946 by Jack McVea, and immediately covered by many other artists, including Fletcher, Count Basie, The Three Flames, and Louis Jordan, all of whom had hits with it. It was the precursor of many similar novelty R&B-based records, which became a mainstay of early rock and roll in recordings by groups such as the Coasters. "That's All Right" by Arthur Crudup, released as a B side in 1946 and featuring Ransom Knowling on string bass and Judge Riley on drums, may be considered a transition song between blues and rock and roll and, arguably, the first rock and roll song according to several sources, including Southeastern Louisiana University rock historian Joseph Burns, who adds that "this song could contain the first ever guitar solo break". One reliable source states that it "stands as a convincing front-runner for rock ‘n’ roll's ground zero". The song was covered by Elvis Presley in 1954 as his first single but Presley's version was "at least twice as fast as the original". "Move It on Over" by
