The Hollywood Bowl opening would’ve been a genteel affair Friday but for the “Grobanites” in the auds.

Following clips, including one with Lisa Simpson, Josh Groban and opera singer Kiri Te Kanawa were inducted into the Bowl’s Hall of Fame as his legion of fans shouted themselves hoarse.

Calling himself a hometown boy, Groban said the Bowl was “a place of inspiration,” adding, “It’s wild. I just met William Shatner before the show. He’s so cool.”

Among those in the aud were Beau Bridges, Eric Idle, Scott Bakula and Roger Daltrey, who was also onstage swinging his mic like a rope as he sang.

But it was Dame Edna who brought the house down. “Kiri Te Kanawa,” she said, was Maori for “gorgeous woman in sparkling dress.”

And then she gave a geography lesson to the Bowl aud. Explaining how to get to Te Kanawa’s home, New Zealand, she said, “You fly to Japan, take a sharp left and, five Ben Stiller movies later, you’re in my home, Australia. New Zealand is like Catalina (off the coast of Australia) or Cuba without Castro.”
