INDIANAPOLIS — Bob Glaze, a beloved children’s TV show personality known around Indiana as “Cowboy Bob,” has died.

He was 73.

The guitar-strumming cowboy and animal lover was an after-school fixture on Indianapolis’ WTTV Channel 4 throughout the 1970s and 80s.

He died Friday at the Community Heart and Vascular Hospital in Indianapolis, his wife, Gail Glaze, said.

Glaze, who started out as a camera operator, became host of the children’s variety show “Chuckwagon Theater,” which later became “Cowboy Bob’s Corral.”

He used the show to engage children in lessons about such things as fire safety and animals. He even taught his dog, Tumbleweed, to demonstrate how to stop, drop and roll.

He was helped by a gang of playful puppets, the most memorable of which he dubbed Sourdough the Singing Biscuit. The inspiration for that quirky sidekick came from a leftover biscuit that was dropped on the studio floor.

Reflecting on his life in a WTTV interview earlier this year, Glaze said he wanted his show to be more than clowning around.

“I wanted to be, if possible, a surrogate brother, father to the kids out there,” he said. “That was my motivation.”

While working as a TV camera operator, Glaze was enlisted to play guitar and sing as a guest on another of the station’s children’s programs. His performance was well-received and he was chosen later to host a new show. Asked what character he wanted to play, the Oklahoma native and experienced horseman immediately chose a cowboy.

In the years after the show went off the air, Glaze appeared at fundraisers and parades and supported animal shelters and YMCA children’s programs.

He and his wife cared for 19 rescued dogs over the years.

“He was actually kind of a shy person, but he was able to take his desire of being a good person and put it into a character to perform and hoping to get the message out that you have to treat one another as equals and have good in your heart and always do the very best you can and just never give up,” Gail Glaze said. “I think that message is pure and it’s simple, but that’s what he was all about.”
