“Pippin” is a rather strange show. Ostensibly it is a production of “Pippin: His Life and Times” as performed by a band of traveling actors under the direction of their wickedly charismatic Leading Player. It is also the story of Pippin and his search for some grand meaning in his life, some sense of purpose. It is also a show that makes you wonder which parts of it are performance, and which parts are deadly real. Finally, it is a show all about the strengths of idealism, the dangers of it, and the need not to be an arrogant prick while pursuing it. With lyrics and music by Stephen Schwartz and book by Roger O. Hirson, ”Pippin” is a singular piece, full of comedy, tragedy, music (of course), and, yes, even just a little bit of magic.
