Broadway Musical On The Porch

I am back in LA and spent the day in the sun with Grace and Em, AKA  Elsa and Anna, princesses of Arendelle from Frozen.  
Eventful and uninterrupted, with no chance to applaud, they belt out song after song until they get to one where they forget a lyric or two. 
The stage is only a little 3-step concrete porch, but this show is destined for a long run.
