Malcolm "Little Mack" Simmons (January 25, 1933 – October 24, 2000)[1][2] was an American Chicago blues harmonica player, singer, and songwriter.

[4] In 1954, he moved to Chicago, Illinois, put together his own backing band, and had a five-year residency at Cadillac Baby's.

[4] In the late 1950s and early 1960s Simmons recorded several more obscure singles, often simply billed as Little Mack (or Mac).

[2] Simmons left the music industry for the ministry in the 1960s and was rarely heard for the next 30 years, notwithstanding an album he recorded in 1975 in Paris.

Come Back to Me Baby (1996), with featured sidemen John Primer, Willie Kent and Jake Dawson (guitarist), was also well received.
