Robert Lee McCollum recorded under the pseudonyms Robert Lee McCoy and Robert Nighthawk - he assumed the nickname Nighthawk after he released an album called Prowling Night Hawk.
After some initial success with Chess - even being compared with Muddy Waters recording and performing in 1951 and 1952, he failed to achieve great commercial success.
In 1963, Nighthawk was rediscovered busking in Chicago and this led to further recording sessions and club dates, and to his return to Arkansas, where he appeared on the King Biscuit Time radio programme on KFFA.Unfortunately after a second go at fame he died from a heart attack.
