Is Hugh Jackman performing every shows of the Music Man or does it have any alter cast of his role? If it has alter cast, how can I know the schedule of Hugh Jackman's performance?

Mr. Jackman plays every night just not the kids they only one that have alter.

There were a couple substitutions of the minor cast members but no substitutions of the main cast

He is but with covid still around if he gets it the show would have to go on with him

With a name that big, they would likely cancel a show if something nakedness where he could not go on.
