Funny, because my 19 year old and I saw "Hello, Dolly!" a few months ago and she said: "Wow, I can't remember the last time I left a musical humming along with the songs. Everyone was memorable in its own way!" Neither of us was all that familiar with Dolly (I knew what I had seen as a kid on the talk shows with Carol Channing but had never seen a production of it.) Jerry Herman wrote some catchy, fun tunes. I really don't find it forgettable at all!
