Lou Busch (né Louis Ferdinand Bush; July 18, 1910 – September 19, 1979) was an American record producer, musician and songwriter, best known for performing, as a pianist under the pseudonym Joe "Fingers" Carr.

[1] At 16, he left school and home for a career as a professional musician, playing with the likes of Henry Busse, Clyde McCoy, and George Olsen.

After Kemp died in a car crash in 1940 and the group disbanded, Busch and Mooney made their way to California to work as studio musicians and on whatever other gigs they could find.

It was around this time that singer-songwriter Johnny Mercer was recruiting artists and employees for his recently formed label, Capitol Records, so Busch was hired for the radio transcription service in 1946.

[1] One summer, Busch played piano for singer Jo Stafford and conductor Paul Weston on the hit record "Ragtime Cowboy Joe".

[2] Sherman explained Busch's choice to change the spelling of his surname: “Lou thought it would look fancier with a ‘c’ in it.”[3] A few later albums were released on the Dot label, and in the late 1970s he produced one more effort with friend and jazz pianist Lincoln Mayorga, complete with a couple of new tunes, The Brinkerhoff Piano Company.
