Oops again. Even bigger oops.
Oleanna is most definitely NOT sold out for all performances. I am apparently not qualified, though, to operate the ticket purchasing page on the Seaside Rep website.
Before learning of my impairment, I took SJ's advice and rushed over to Seaside and saw the dress rehearsal. It's very well done indeed. Buy one of the READILY AVAILABLE tickets and go see it.
The dress reheasal was a great way to see the play. After the performance, the audience (all 7 of us) had an informal discussion with the actors about the characters and the play. I'm sure they were interested in seeing if we read the characters in the way they intended. From our end, it was just as revealing to see their reactions to our comments. I don't know if this is the way they always do it, but I'd happily go to another dress rehearsal.
Highly recommended.
