After seeing a message on Stargreen's site ("no web
tickets for Waits - phone instead") I rang them and
they told me that they have no tickets left, on or
off line. Also, the other agencies they deal with
were all sold out.
I asked how many they sold online, since there was 1
left at 9:02 (!) and they said they'd sold a few, but
the way they said it indicated they didn;t sell many.
So, as i suspected earlier, I think they resorted
entirely to phone bookings. Sold out within the hour
apparently.
