I can't say any shows have touched me so deeply emotionally where I cried for the pure fact of the show....Although, I was misty eyed on my way to tears a couple weeks ago when I saw Mamma Mia! for my 7th time...I was sitting next to my mom, and it was during 'Slipping Through my Fingers,' seriously, guys; i'll be leaving in due time, so it was extremley painful to sit through; I almost started balling.
And, the 2nd (and last) time I saw The Wedding Singer...at the time I didn't know it would be my last, but I got to see Tina Maddigan perform, and i'm a huge fan. We almost couldn't get tickets, so I was crying before hand (heh), and then afterwards, I figured it would be one of my last times seeing the show, so it was all sad at curtain call since I got to see this women I'd been a fan of for years perform the leading role in one of my favorite shows...
Anywho, enough of my rambling, carry on :]
