In the stage production I saw in Boston (featuring Ted Neely and Carl Anderson), Jesus, on the cross, said the line and then was lifted up towards heaven (the rafters) as the curtain dropped. I am not an emotional guy, and I had to fight back tears. My girlfriend (now my wife) wept openly, and so did several other people in the audience.
That would have been cool.
You know what always makes me cry? It's the scene in Godspell where everyone is taking off their makeup during the last supper. I'm tearing up over that one even now.
It must have been so hard to say goodbye to Him. I really don't know how the disciples were able to stand the heartbreak.
Shalom.
