Sixty plus years ago, Gertrude Lawrence starred in musicals by the Gershwins, Kurt Wheill and Rodgers & Hammerstein
Her husband owed a Summertheater on Cape Cod and Gertie appeared there frequently in musicals and plays. Thus her name was frequently in the news.
Mary Martin and her husband owned the rights to Maria von Trapp's life story and worked with Rodgers and Hammerstein together.
Not sure if actors are so involved financially now. But stars stay with musicals when they understand the financial aspect of musicals and plays, I think.
Lawrence died when she was still the star of "King and I."
