Robert Lee McCollum (November 30, 1909 – November 5, 1967) was an American blues musician who played and recorded under the pseudonyms Robert Lee McCoy and Robert Nighthawk. He was the father of the blues musician Sam Carr. Nighthawk was inducted into the Blues Hall of Fame in 1983.

McCollum was born in Helena, Arkansas. He left home at an early age and became a busking musician. After a period traveling through southern Mississippi, he settled for a time in Memphis, Tennessee, where he played with local orchestras and musicians, such as the Memphis Jug Band. A particular influence during this period was Houston Stackhouse, from whom he learned to play slide guitar and with whom he performed on the radio in Jackson, Mississippi.

After further travels through Mississippi, he found it advisable to take his mother’s name. As Robert Lee McCoy, he moved to St. Louis, Missouri, in the mid-1930s. Local musicians with whom he played included Henry Townsend, Big Joe Williams, and Sonny Boy Williamson. This led to two recording dates in 1938, the four musicians recording together at the Victor Records studio in Aurora, Illinois. He also recorded under his own name, including “Prowling Night-Hawk” (recorded 5 May 1937), from which he took his later pseudonym. These sessions led to the other musicians pursuing Chicago blues careers.

But McCoy continued his rambling life, playing and recording (for Victor/Bluebird Records and Decca Records) solo and with various other musicians, under various names. Kansas City Red was his drummer from the early 1940s to around 1946.^[8] He recorded Kansas City Red’s song “The Moon Is Rising”
