A half-hour produced in Montreal, Nightcap was a very informal musical variety program, set in a cabaret. The host was Alan Mills, who played the club's patron; William Robert Fournier, another regular, was the waiter. Mills would circulate among the studio audience, in which celebrities were planted, to talk with his guests and perhaps to convince them to do a number. The program also featured singer Nina Dova and pianist Gilberto Assais.
