Not POTO, but musical related nonetheless. This was a presentation made in honor of Stephen Sondheim's 75th Birthday. It features the cast of a TV show made by a gay guy who is quite clearly obsessed with Stephen Sondheim, the funny thing being that most of the episode titles for the show are titles or lines of songs Stephen Sondheim wrote.
Such episodes include
"Ladies Who Lunch"
"No One Is Alone"
"It Takes Two"
"Listen to the Rain on the Roof"
"Into the Woods"
"Gossip"
"God, That's Good"
"Sunday in the park with George"
There are only seven episodes not named for SS songs, but are still alluding to songs such as the episode "Anything You Can Do"

P.S.- The show... is Desperate Housewives.
