The Serendipity Singers Show is SO totally classic 80's. It's kind of a cross between Solid Gold and Hee Haw. There's singing of 80's songs by members of the traveling group mixed with the occasional corny skit. Having been done in the '80s, it has all those cheesy video effects and camera tricks of the day.
What makes it so great is that it was done completely seriously at the time, but now has that cheese factor that makes it incredibly, hilariously funny.
You have not lived until you've seen the "Eye Of The Tiger" video as performed by the Serendipity Singers.
