A recent conversation amongst friends brought this interesting question.
Among the longer-running game shows (including multiple versions and gaps between versions ), what are the 5-10 oldest themes that have more or less kept the same melody in continuity?
First thought was Jeopardy!, but you could only count the years since Trebek started the show. The familiar theme was only used as the Final Jeopardy think music in the 1st Fleming version.
Pyramid was another possibility, but Donnymid broke the streak.
Price is Right could only go back to Barker's start, but it seems like that theme melody is the oldest lasting continuous theme -- different arrangements but still the same melody throughout.
Supermarket Sweep is another possible Top 5 contender even if you only count David Ruprecht's versuins.
What would also be themes that have remained more or less intact the longest?
