I just sang Phantom of the Opera in a concert. I took the last bar scream-y, three Es above middle C bit down an octave, but someone told me it was the best act in the show, and given the standard of some of the performers, that's a compliment of the highest order... Everyone said it was good, in fact.
I missed one note, but all the scary, top of my range ones were really secure. That's made me really happy.
Now I just have to try and do it again tomorrow night.
