Red Skelton collapsed during a benefit performance in Honolulu but returned to the stage as the audience sang "Happy Birthday" to the veteran comedian-clown who turned 75 Monday, an organizer of the event said.

Skelton, overcome by heat and humidity, collapsed into the arms of the sound crew as he left the stage 90 minutes into his two-hour outdoor performance Sunday night, said Lynn Cook, executive director of the March of Dimes Chapter of the Pacific."I'm really not feeling well. I'm going to have to leave you. I'm very sorry," Skelton told the audience before he collapsed, according to Cook.

Comedian Milton Berle, who turned 80 last Tuesday, came up from the audience to take over the microphone as his wife, Ruth, and Skelton's wife, Lothian, rushed backstage, Cook said.

Skelton was revived with the aid of an ambulance crew that administered oxygen, returned to the stage and finished the show.

Sunday's high in Honolulu reached a rec-ord-tying 90 degrees.
