Wow, so many favorite tunes listed by all of you. Many of those songs are also part of my favorite list, but I have to add several more--(not an all-inclusive list, to be sure):

In the Wee Small Hours of the Morning
When I Fall in love
They're Writing Songs of Love (But not For Me)
Just about anything by Irving Berlin (one of the most underrated composers of our time, I think--a true genius. By the way his birthdate and mine--May 11--are the same day--although a few years difference); and he was so much better a composer than I am!!!
Maria (from West Side Story)
I've Grown Accustomed to Her Face
You'll Never Know (just how much I love you)
Singing in the Rain

My list is just the beginning, but enough for now. My very favorite? I would have to say Over the Rainbow, a song I consider an incomparable masterpiece of music and lyric. And I know I have forgotten dozens of others that I really also love.

One classic, or semi-classic, that turns me to mush, and makes me weep when I hear it, is the 18th Variation of Rachmaninoff's "Variations on a Theme of Paganini" (you should listen to the entire piece, however, to enjoy the incredible buildup to the 18th. I get chills just thinking about it!). And anything by Puccini.

Lots more, but enough for now, my dear friends.
