The San Diego show has been cancelled due to poor ticket sales. Tickets can be returned for a refund, or traded in for seats to the Irvine show and admittance to the soundcheck.
from Camden C.:
So I had 3rd row center seats for this concert and the story I heard at the time was that Robert and his wife were having marital problems and he had to go back to England, and that's why the show was cancelled, not for poor ticket sales. We turned in our tickets and got nose bleed seats for the Irvine Meadows concert that year.
