CHOCOWINITY — Southside High School’s cafeteria will be rocking next Friday night, and it’s for a good cause.

On March 28, the band K-OS, whose rock repertoire spans decades and genres, will headline a Relay for Life benefit concert. Admission is $3 per person, hot dogs, baked goods and drinks will be sold — the proceeds of which will be donated to the international organization that funds cancer research, as well as support programs for those battling the disease.

K-OS’ five members are all local boys: Greyson Schmitt, Connor Smith and Zack Pagnani attend Washington High School; Caleb Petty is at Chocowinity Middle School, while Kendall Smith attends PS Jones Middle School.

As a band, the guys are becoming well known for pitching in their musical talents for local fundraisers, playing a recent Darleen’s Flamingo 5K in Belhaven and another show at an Angels N Camo fundraiser, among their festival and private party gigs. But the Relay for Life benefit touches a little bit closer to home. According to Tina Petty, K-OS drummer Caleb Petty’s mother, their family lost two cousins to cancer last year and Caleb’s aunt was diagnosed with the disease last summer.

“Cancer has kind of hit our family hard in the past year,” Tina Petty said.

The Pettys’ connection to cancer led to the idea for the benefit concert.

“Basically, my son was the one that decided to become a part of Relay (for Life),” Tina Petty said. “And since it was the band joining, we decided to do the fundraiser.”

A math teacher at Southside High School, Tina Petty approached Southside Principal Dale Cole; his response, “We’d like to support Relay for Life, so why don’t you have it here?” set the plan in motion, she said.

Teachers and staff have jumped on board as well, providing the home-baked goods for sale and signing up to sell food and beverages. Luminaries, to honor or remember a loved one who has had cancer, will also be available, and the band will recognize cancer survivors who are present with a song dedicated to them.

“All of the proceeds from the admissions to the food sales will be donated to Relay — every bit of it,” Tina Petty said.

The event will run from 6:30 p.m. to 9 p.m. and is open to the public. Tina Petty said organizers are looking for a big turnout.

“As many people as we can get — we’ll take them all,” she said. “We want it to be a big success.”
