Bobby Troup was a songwriter and lyricist whose work bridged swing-era pop and jazz. His songwriting career began in the late 1930s and produced hits across several decades. His first major commercial success, "Daddy," reached number one on the Billboard chart in 1941 and held the spot for eight weeks. His most famous composition, "(Get Your Kicks on) Route 66," was written in 1946 during a cross-country drive to California and recorded by Nat King Cole almost immediately, becoming a million-seller that has since been covered by dozens of artists from Chuck Berry to the Rolling Stones. Other well-known songs include "Baby, Baby All the Time," originally conceived while Troup worked as a writer for Tommy Dorsey, "Girl Talk," and "Snootie Little Cutie," recorded by Frank Sinatra. Troup also performed as a jazz pianist and singer, and he produced recordings for his wife Julie London. His songs were recorded by a wide range of artists including the Page Cavanaugh Trio, Sammy Kaye, and Ruth Etting, reflecting a catalog that moved comfortably between pop, swing, and the jazz idiom.
