Happy Holidays from Milwaukee! I just finished posting a new page on my website about Leonard Nimoy's appearance as Fagin in OLIVER! (1972) at Melody Top Theatre. There are some awesome photographs of Mr. Nimoy, both in and out of his Fagin costume. Even though he never played a musical role on Broadway, his singing in stock and regional theatres was given high praise from local critics. Click on the link in this message to learn more about OLIVER! and Mr. Nimoy's impressive stage work.
In Jay Joslyn's review of this production, he stated the following: "In some kind of attempt to achieve a different atmosphere, Bishop has allowed his actors to paint their faces in a most distracting manner." I'm not sure why this was done, but some of the characters were portrayed (with the use of make-up) as having animal features.
It's funny to me that I saw this production from the first row and don't remember the weird makeup. Maybe they gave up on it by the end of the first week. Or maybe I was too focused on how good Leonard Nimoy was, including his singing. The newspaper article you included about how these summer stock shows were put together in a week, while most of the company was doing performances of another show at the same time, was nothing short of mind boggling!
Since the effects of extreme poverty are an important theme in both the original novel and its musical adaptation, the painted faces on performers in this production of OLIVER! may have represented humans living like animals. I think I remember seeing cartoons from Dickens' time that featured animals dressed in ragged clothing, representing the very poorest members of society.
