But those attending should be aware that the goodies being handed out at the door are not for human consumption - they are for their cats.
King's High School assistant principal and show co-director and producer Bryan Frost said the annual King's and Queen's high schools' production managed to gain sponsorship for the show in the form of Whiskas cat food.
The idea came from the discovery of an old programme from a professional season of the show staged at the Regent Theatre, in Dunedin, during the 1990s.
The programme contained a full-page ad for Whiskas cat food.
"So we thought it would be great to copy it," he said.
"Cheekily, we asked for sponsorship money to cover programme costs. They said, 'We don't do money, but we will send some product'.
"So, now, every programme sold will be accompanied by a packet of Whiskas cat food."
Mr Frost said they had received about 600 packets and those who did not want them would be encouraged to drop them in a bin at the door for the SPCA.
The production opened last night and ends on Sunday afternoon.
