Reader Joe Marchese confirms…
RE: Fiddler on the Roof, you've got it right, and the L.A. Times got it wrong. Luther Adler did indeed fill Zero Mostel's rather large shoes as Fiddler's second Tevye, first while Mostel was on vacation (1/18/65-1/30/65). He then took over the role on 8/15/65. While I don't have the date that Adler wrapped up his run, Herschel Bernardi didn't take over until November 8, '65.
Good to know. This is interesting because, when Mostel left Fiddler, it was reportedly with a near-certainty that he was the show and it would not long survive without him. And of course, it did close…seven years later.
