A popular adage proclaims that it ain't over till the fat lady sings. At the end of the madcap You Can't Take It With You, Stray Dog Theatre's ode to eccentricity, everybody sang cast and audience alike. Never mind that this wasn't a musical. After the play had ended and the bows proper were done, the play-ful actors tore the place apart with a free-for-all sing-along version of "Goodnight, Sweetheart." It was a deft reminder that shows aren't over till the last light is out. The captivating production left us with a smile on our faces; the all-embracing curtain call sent us home with a song in our hearts.
