Firstly, I'd like to say "stop moaning" to all who say Streisand was too young to play Dolly Levi. She did an amazing job of it and both her acting and her singing are spot on. In fact all of the performances in this film were great.
This musical is about a young widow,Dolly Levi,who is matchmaker to Horace Vandergelder, the unmarried half-a-millionaire, but decides she wants him for herself and disrupts his and everyone around him's life in a day of much singing, dancing and general mayhem. But, after a lot of hiding, parading, posh restaurants and plotting, all works out perfectly for everyone in a glorious finale.
With great singing, dancing, acting, good script and funny lines, Hello,Dolly! is a brilliant musical, that you absolutely MUST see!!!
