There are three knockout moments in Front Porch Theatrical’s production of Alison Bechdel’s autobiographical musical Fun Home..And the third happens in the number “Telephone Wire,” in which Alison (Drew Leigh Williams, playing Bechdel as an adult) relives the memory of her last opportunity to have a conversation with her father, Bruce (Daniel Krell), who committed suicide shortly after that visit home from college...For those of us of a certain age who were raised by similarly silent, stoic fathers, such regret is poignantly familiar, and Williams traverses the whole range of complicated emotions their stubborn secrets provoke, from anger to bewilderment to deep yearning for a truth that will never out.
