Well I have never bawled hysterically..but some of the songs or scenes where I have become moved emotionally to the point of tears are:
1) From "Make them Hear You" through the finale of RAGTIME (when little Coalhouse runs out)--EXTREMELY MOVING!!
2) The finale of TITANIC--when the living join the dead for the reprise of "Godspeed Titanic"
3) The "Where in the World/How Could I Ever Know" scene in THE SECRET GARDEN when Archie is on the brink of suicide
4) as mentioned many times over...."A Little Fall of Rain" from LES MISERABLES
5)From "All the Wasted Time" through the finale of PARADE...the "happy memorial day" line gets me every time!
6) "If I Loved You" reprise from CAROUSEL-- when Billy realizes how much he truly loved Julie and how awful he treated her AND "You'll Never Walk Alone" (both times)
Wow..I could go on and on and on....but I will spare all of you and limit it to 6! :)
"You pile up enough tomorrows, and you'll find you are left with nothing but a lot of empty yesterdays. I don't know about you, but I'd like to make today worth remembering." --Harold Hill from The Music Man
