"I think I knew one George Strait song," she said. Finally, she bargained with Josh, telling him if he would hire her three days a week at the music store, she would sing in his band.
The partnership worked, and then some - the two ended up as a couple.
Three years ago, Josh decided he wanted to turn to bluegrass instead. He recruited his dad, and the three began practicing with a fourth member, who has since left the group. Cousin Danny Ray now plays guitar with them.
Their first gig - gulp - was the Wheeling Jamboree, at which they were asked to play for an hour. Pam made her debut on the bass, now an old friend named Rosie, and recalls her hands shaking when they took to the stage.
More gigs followed, thanks to the good reception from the jamboree crowd, and from lots of boots-on-the-floor marketing.
"We'd give out CDs in parking lots," Pam said. She created a Facebook page and wasn't afraid of making cold calls.
While Josh has lots of training, thanks to a former music student who then later, as a college student, taught him how to read music and music theory, Pam is self-taught. She can't read music, but she can learn a song quickly thanks to a photographic memory.
She describes herself as having been a headstrong, ornery child. To calm her down, her mom sat her down and made her learn gospel songs.
By 10, she was singing in church, up front and solo.
She only recently started learning harmony lines, so accustomed was she to singing lead.
Josh said bluegrass is best learned hands-on, anyway.
The band takes no written music to gigs, not even cheat sheets of words. They know 150 or so songs by memory.
"All we take with us is a set list," Josh said.
He believes their appeal lies in a sound that harkens to old-time country and bluegrass. Pam has been told she sounds like Tammy Wynette or Patsy Cline.
"She sound like everyone and no one," he said. "When she sings, she doesn't lose her country accent and people like that."
Josh said he's an instrumentalist at heart and only recently began singing.
"The blend of our voices is unique to itself," he said. "People say they've never heard a sound like ours."
One of their favorite things is lending an unexpected bluegrass twist to a pop song - Adele and Fleetwood Mac in bluegrass? Why not?
"We call it Fleetwood Grass," Pam joked.
