Apologies if I've somehow missed it, but is there sheet music for Hadestown?  I see a book of lyrics is due in April, but I can't find piano / vocals anywhere.  I'm hoping this is just a silly search-fail on my part and not an actual lack of sheet music!  Any help / advice would be much appreciated.  

We got there at 7:45am on a Wednesday morning (today). We were 15 and 16 in line.  Got tickets no problem.  I think they went through about 65 people on line.  But there were many unsold tickets and there were two shows.  Have no idea if that's something you can rely on.  

Here on Tuesday Aug 20.  Our group of 5 arrived super early at 11am.  At 12:45, 1 other person arrived.  (So at 1pm there are six total so far.)
