Clad in a collared shirt and respectable khakis, Andrew Alford was every inch of business casual as he took a seat outside of Tipsy McSway’s in downtown Brunswick.

Looking at him, you’d never guess he belongs to an eclectic rock and roll group. As his bandmates begin to appear though, Alford’s cover is blown.

Dalton Rooks saunters through Jekyll Square outfitted in brown overalls sans shirt, a guitar dangling from a rainbow strap over his shoulder. He takes a seat next to Alford, who can’t help but smile.

“Nice outfit,” he offers with a laugh.

Rooks nods with satisfaction as David Silva appears. He’s wearing a blue sleeveless Hawaiian shirt, purple flamingo suspenders, and shorts. Alas, as a drummer, he wasn’t able to bring his instrument.

Patrick Langley rolls up to complete the picture in a cosmos-themed tank and light blue bandana, clasping his trusty horn.

“I guess you didn’t get the memo,” Langley says to Alford as the other bandmates snicker.

But, just in time, a red sleeveless Miller High Life shirt materializes and Alford is saved. Doink has officially arrived.

This band is a lot of things — loud, bold, boisterous — but business casual ain’t one of them. This fabulous foursome is about bringing big sound in unexpected ways.

In fact, everything about this group has been unconventional, even the way that it began. The four musicians seemed to fall together by pure happenstance.

“It was about two or three years ago. I ran into David at Open Mic Night at Palm Coast. I’d known him for two or three years,” Alford recalls. “And he asked me if I still played bass. Then, he said, I know a guy who plays guitar ... do you want to come back next week and play?”

That would be Rooks. The trio started playing together during the event, just making it up as they went along.

Langley, who was working at Palm Coast at the time, became a fan.

“I’d be behind the bar and I would switch the house music inside to the stage to listen to them,” he says.

Eventually, Langley was invited to join the band and the group was set. The name, however, was a little more up in the air.

“We had a bunch of unofficial names. We’d sign up under silly names, because at the time, it was just the three of us so we’d be Dirty Dalton and the Cooks. I know we were Mouse Rap once,” Silva says.

“One night, we signed up as Doink and it stuck,” Alford adds. “Our buddy Filo got up and started free stylin’ about Doink.”

Word started spreading about the shiny new band and its onomatopoeia of a name.

“People started asking us when Doink was playing again ... so I guess they decided because we weren’t really even Doink then,” Alford says with a laugh.

The name clearly works. It seems to capture the group’s quirkiness with precision clarity. Not only is their style a little wacky, their set lists are also bit unorthodox.

They typically play rock and funk songs, but in a way that people have never heard before.

“There’s a real improvisational aspect to it,” Alford says. “The same song can sound completely different.

“We nail it in the moment,” Langley says. “We do a lot of songs that we’ve never practiced before and it just happens.”

But considering each of them has been playing for decades, picking up new tunes comes fairly easily. Rooks adds that their spontaneity brings something unique to the area’s robust music scene.

“We wanted to offer something different. We didn’t want to play things that people are already playing,” Rooks says.

Doink will be jamming at PorchFest in downtown Brunswick on Nov. 14. They have also played at Tipsy McSway’s in Brunswick and Village Creek Landing and Murphy’s Tavern, both on St. Simons Island.

“We’re going to have to learn to play a little softer ... Doink isn’t really a dinner music kind of band, but we can learn to bring it down a little,” Silva says.

One thing that won’t change — Doink’s carefree character.

“That’s what I really like about this band. It’s so much fun. I’ve been in bands before and some folks will be really serious about it,” Langley says. “With Doink, no one takes it too seriously.”

“It’s all positive energy and good vibes,” Rooks adds.
