Lovelorn music man Lester the Nightfly, a major player on Donald Fagen’s 1982 solo album The Nightfly, is a character with a complex identity. At first contemplation, he’s a jazz DJ on the nightshift during the golden, Camelot era of American life in the early ’60s, fielding calls from a cornucopia of after-hour nutsos while holding steady with his jazz heroes whose music he showcases across the night and out into the airwaves.
