Madame Butterfly

There are a few notes on the backs of these photos, but they don't really tell us much.  The top, "Harry-1" the next, "Heloise, Don, & opera company," and the bottom, "Denise Webb 1 picture,  Norm -1, Cast Madame Butterfly."  I've seen more than a few plays performed in schools and churches, but never an opera,  and it does look like this is an amateur opera group, performing in a church.
