First one I was to see was West side story. Got me hooked.
Then south pacific, that I went bonkers over because the director used the weird coloring for the song Bally High. really pissed me off.
Then Hair, Jesus Christ super star, Cabaret, Fiddler on the roof, Chicago that Hubby has watched 20 times, and perhaps 10 more that don't come to mind at this time.
Then the TV Xmas shows especially the one with the Elf that wants to be a dentist, Ah so soon they will be played again this year.
All the old time movies b&w with dancing and the WW2 movies with the USO as a topic.
Bob Hope and Bing Crosby in the road movies, the westerns with Gean Autery or Roy Rogers.
