Mark Evans shines in Rodgers and Hart’s 1938 hit “I Married an Angel”; this dance infused fantasy story involving an aristocrat who literally marries an angel is a peculiar relic of its time, but a treat for collectors of obscure musicals and fans of the Rodgers and Hart oeuvre. Director/choreographer Joshua Bergasse steps into the shoes once worn by George Balanchine to create an entertaining show featuring the talents of ballerina Sara Mearns (his wife), as the Angel. Feather-light as it is, I suspect we won’t see “I Married an Angel” again for some time.
