Musicale

I love musicals. I can remember the very first one that ever stole my heart was Oliver! I was living in South Carolina with my dad at the time, and the place where I slept was the family room. I remember sitting in front of the console television crying as I watched Oliver ask for "more", giggle as he learned to pick-a-pocket-or-two to a catchy little tune, sobbed when he cried for his mother as he sang "Where is Love?" and felt my spirits soar with "Who Will Buy This Wonderful Morning". I could pretty much sing every word to every song even now. Thanks to the miracle of DVD I can watch it whenever I want.
There's Fiddler on the Roof, The Sound of Music, Scrooge, Rent, Chicago, Moulin Rouge, The Phantom of the Opera, High School Musical, Seven Brides for Seven Brothers- some of which I like more than others. Tonight we are watching Oklahoma - and it's pretty good.
What are some older movies that you like? I could use some recommendations. I want to rent some through Netflix - but I hate getting them home only to realize they are duds. Recommendations please??? Not just musicals - any older movies would be muchly appreciated.
