One of my favorite shows from the 80's was the comedy Cheers. I especially loved the early episodes with Sam (Ted Danson) and Diane (Shelley Long). They were a great pair and had such good chemistry. I lost interest in the show when Shelley Long left in 1987. She got too big for her britches and thought she could have a movie career but it never really took off. I also really enjoyed the lovable character Coach, played by the late Nicholas Colasanto.
Cheers is being shown on the Hallmark channel these days. I'm sure you'll enjoy it if you've missed it somehow! Here is a clip of the wonderful theme song (one of the best ever)!
