LaCour was born in 1932 in Louisiana, where his parents were corn and cotton farmers on the Isle of Brevelle.
[2] Lenny LaCour's career in music initially commenced as a performer and songwriter, based in Chicago.
LaCour's Creole heritage enabled him to move freely between Chicago's black and white nightclubs during the early 1950s.
"[2] From 1952 to 1956, LaCour released several singles on the Chicago-based All American, Spin and Meteor labels.
[1] As described by Dik De Heer: LaCour's break came in 1956, when he won a Chicago jingle contest for Orange Crush, the soda bottling subsidiary of Pepsi-Cola.
In Milwaukee, LaCour had more success recording local acts than in Chicago,[1] particularly in relation to Harvey Scales, who co-wrote and released "Love-Itis" and was the later co-writer of "Disco Lady".
"[2] In 2008, the album Walkin' The Bullfrog (Night Train International) was released, which provided a career overview of Lenny LaCour's solo recordings.
