On Saturday Night (A Little Fun —) (With SNL Cast)
Album 3 (VHS): Saturday Night Live, Warner Home Video 085392902132, 23 August 1989; DVD: Universal Studios, 13 March 2011 – both with this SNL episode (#051, aka season 3, episode 5).
The show aired on 12 November 1977. At the end Ray performed a 1-minute ditty – titled (A Little Fun) On Saturday Night – with the cast of SNL. I don’t know if the ‘tune’ existed before, or if they made it up for this occasion.
