The applause was long and loud at the end of the performance (as it always is at ballet) but the choreographer looked very pleasingly surprised by the reception. I also applauded the lady next to me who during the performance ripped into a guy on the row behind who got his phone out in the middle of the performance (presumably to take pictures). The brief scene caused was immensely better than just being polite and letting him annoy everyone with his bright screen, and it's very hard for a 20 something guy to argue with a 60 something lady.
The flamenco singer was off stage. In true opera style she could probably be called 'a lady who loves cakes'.
