Anybody remember the "Joseph and his Brothers" drama from the early 70's? That's the only one we were in (I should say Clyde). I believe the drama was about showing forgiveness. Clyde played the part of "Dan", and we thoroughly enjoyed the drama--except for one thing. Clyde decided to grow a real beard instead of using one of the fake beards. He looked great in his real beard but they asked him to shave it before the assembly. To keep the peace, he complied.
Like Blondie said, I think they used to stick closer to the actual Bible account as we could just about follow along in the Bible.
