In his comic depictions of drunk dancing, Astaire used choreography to project social views and feelings about drunkenness, and to set up tensions between those qualities of inebriation and the precision and agility that his dancing embodied.
Memorable examples include the solo number “One for my baby (and one more for the road)” in The sky’s the limit (1943, above and below).
This according to “Stepping high: Fred Astaire’s drunk dances” by Sally Banes, an essay included in Writing dancing in the age of postmodernism (Hanover: Wesleyan University Press, 1994, pp. 171–183).
