It doesn't have to be performed by a cast of four. I saw a wonderful production by the 4th Wall Theater Company in Morristown, NJ during September, 2002. They had 10 or 11 in the cast. The interpretation of the songs was used to pay homage to 9/11 on the first anniversary. I liked it so much that I went back three weeks in a row.
