I asked Keith Edwards about it and he said his father passed away before completing the musical, then he (Keith) and his wife finished it, but it hasn't been produced. He may comment further.
From Keith's bio:
“Ramses—There’s No Room in My Tomb!”—a musical comedy started by his father, Sherman Edwards (1776) and completed by Edwards (music and lyrics) and his wife Elizabeth (book and lyrics) about the great Ramses II during the final year of his life and the worries over his successor, ensuring his legacy and preparing for the afterlife." |
