Oh my goodness, you need to be introduced
So, it's one of those amusing fluffy little musicals set at a high school with people hooking up and sports stars and nerds and the new kid and whatnot where things that are outside the norm are a case for concern, because hey that's high school and America, huh?
Difference being, it's in a sort of alternate universe. Specifically, where homosexuality is the norm, and your average mid-western school is more than a little heterophobic. The chess club are the ultimate sex symbols, and everyone wants to be cool enough to be in the school musical, while the football players are the losers who get pushed around. Anyway, it follows the adventures of Zanna, the high school matchmaker who tries to make sure everyone falls in love and ends up happy, but struggles when it comes out that a girl and boy have hooked up in a straight relationship and the resulting heterophobic fallout.
Here's a couple of songs from it (whole album is on youtube)
I Think We Got Love (ridiculously cute song of two boys falling in love):http://www.youtube.com/watch?v=qZosCujRdUs
Be A Man (from the school musical about heterophobia in the army, this always gets stuck in my head): http://www.youtube.com/watch?v=btoVQLGc5WE
The whole thing is just so adorably cute, that I want to smish it if that's possible with a musical. The music is sweet and catchy and the show has some nice, amusing and clever ideas - sugar with a point
Saw a great production of it by RSAMD at the Fringe a few years back.
