the definitive vocal version. Young later made an instrumental recording with Nat King Cole and Buddy Rich. "More Than You Know" is a Broadway show tune composed by Vincent Youmans with lyrics by Edward Eliscu and Billy Rose. Introduced by Mayo Methot in Great Day, the song became a hit even though the musical only lasted for 29 performances. Ruth Etting took it to number nine in 1930, and saxophonist Benny Carter played an acclaimed trumpet solo on his 1939 recording, despite the trumpet not being his main instrument. "Rockin' Chair" is a song by Hoagy Carmichael. It was first recorded by Louis Armstrong in a duet with the composer. Carmichael has said that he wrote the song as a kind of sequel to his 1926 "Washboard Blues", which had lyrics by Fred Callahan. The song was made famous by Mildred Bailey, who used it as her theme song. Bailey's first hit recording was made in 1937. "Stardust" is a song composed by Hoagy Carmichael with lyrics by Mitchell Parish. Originally recorded by Carmichael as a mid-tempo jazz instrumental, the 1930 romantic ballad rendition by Isham Jones and His Orchestra became a top-selling hit. Louis Armstrong recorded an influential ballad rendition in 1931. The song is arguably the most recorded popular song, and one of the top jazz standards. Billboard magazine conducted a poll of leading disk jockeys in 1955 on the "popular song record of all time"; four different renditions of "Stardust" made it to the list, including Glenn Miller's (1941) at third place and Artie Shaw's (1940) at number one. The title was spelled "Star Dust" in the 1929 publication, and both spellings are used. "What Is This Thing Called Love?" is a song written by Cole Porter for the musical revue Wake Up and Dream. It was introduced by Elsie Carlisle in London. Ben Bernie's and Fred Rich's recordings made the charts in 1930. One of the best-known instrumental versions was recorded by Clifford Brown and Max Roach with Sonny Rollins in 1956. The song's chord progression has inspired several later compositions, including Tadd Dameron's bebop standard "Hot House". Notes Bibliography Reference works Rawlins, Robert (2015).
