Rare is the musical that begins with an undescended testicle. But that’s the opening parry of Fixing Frankie, by Joe Langworth (book and lyrics) and Steve Marzullo (music). More than the troubled hero’s scrotum needs fixing, and Langworth and Marzullo take him down some curious byways, piling on unnecessary details and side stories. Ultimately, though, Frankie’s healing is a touching little story, if one that could use a little touching up.
