I really am a cry baby

I'm not a big fan of Broadway musicals, I can sit through them and there are a few that I actually enjoyed. But today I was working on putting a DVD together for a friend's wedding and I did a slideshow to Jill Sobule's version of Sunrise, Sunset (from Fiddler on the Roof). I was weeping. Literally. I've heard other versions like the hideous Robert Goulet rendition and of course the high school spring musical versions and they had no effect. I even played this thing several times and cried every time. Am I a big cry baby? Is it because I have a child now? Or is it just the way that Sobule sings the song?
