Obscurity factor: 9
After her eponymous 1976 series (The Nancy Walker Show, produced by Norman Lear) tanked, Walker had just enough time to step into this mid-season replacement show (during the same season!) about the trials of putting together a Vegas show. The series was produced by Gary Marshall and featured actors who had made good on other series in his stable, including Eddie Mekka (Carmine Ragusa from Laverne and Shirley) and Scott Baio. There were lots of ties to Happy Days and Laverne and Shirley, though the series was set in then present day Las Vegas - Eddie's character was Carmine's younger cousin, there were references to Laverne, Pat Morita joined the cast (he owned the drive-in in Happy Days) and Pinky Tuscadero even made an appearance.
Above is the show open with a short introduction that was aired only on the pilot. The series ran for 13 episodes and was then cancelled. Needless to say it hasn't made it to DVD.
