Two Late Nights aired on September 25, 1986. The first was a new show that broadcast in place of the Tonight Show, which had celebrated its 24th anniversary earlier in prime time.
The second Late Night followed in its usual 12:30 am slot; it was a rerun from February 17, 1986, but with other voices replacing everyone who was on the show.
Peter Fernandez was the voice of Dave; Earl Hammond as Paul; Corinne Orr as Raquel Welch; and Maya Danzinger as Sandra Bernhard, with LN writer Randy Cohen supplying additional voices.
