McDonald’s 1986 advertising campaign featuring a crooning moon-faced character was called Mac Tonight.
The campaign promoted McDonald’s evening business and used a character with a crescent-moon head, dark sunglasses, and a tuxedo. Mac Tonight sang a rewritten version of “Mack the Knife,” changing the lyric to emphasize the evening and nighttime setting.
Mac Tonight was introduced in 1986 and became especially associated with late-night restaurant visits. The character’s style differed from the brightly colored McDonaldland cast: it used lounge-singer imagery, a piano performance, and a more adult-oriented musical tone.
The campaign is sometimes confused with a general McDonald’s nighttime slogan or with the restaurant’s modern late-hours branding. Mac Tonight was specifically the name of the advertising character and campaign, not the name of a menu item.
