Who was in the cast for the Thursday 27th May Matinee?

I went to see Priscilla today as it will be the last time I will get to see Jason Donavon in this show. It was my 3rd time seeing this show and it was the first time seeing the new cast. I just wonder was it the full cast on for the matinee? Anymore know who played Bob,Marion and Benjamin in the matinee? I might be wrong but I thought it was Jeremy Secomb on for Bob today. I prefer Clive Carter as Bob. All in all another great show.
Also what is all the fuss about Don in this show. I thought he was great. He was a bit different to Tony and a bit more like Terence Stamp.
