On Friday-Saturday, March 11-12, the West End vet will perform “Sondheim’s Divas,” a show that has him belting out songs usually performed by characters who identify as female. On Sunday, March 13, McArthur will sing and tell stories in “Mountain—A Musical Adventure,” an autobiographical show about his career in showbiz here and across the pond, liberally peppered with iconic show tunes.
