There is probably more than one disc jockey who used this moniker, just like there are pluralities on "Mr. Latenight," "Great White Disc Jockey," "Funky Dawn Man," etc. The Nighthawk was into the jazz fusion thing, operated out of a northern California beach town while everyone else except hipsters was asleep, and was the inspiration for the character played by Adrienne Barbeau in John Carpenter's horror film The Fog. ~ Eugene Chadbourne, All Music Guide
