A few hundred people are expected for the concert and memorial service in Beavertown, where the singer of "Daydream Believer" and "Last Train to Clarksville" fell in love with a rolling landscape that reminded him of his native home.
"He said, 'This is just like England,'" Mayor Cloyd Wagner told The Philadelphia Inquirer.
Jones died Feb. 29 of a heart attack in Florida but spent much of his time in Beavertown, about 150 miles northwest of Philadelphia. He settled on a 15-acre spread on the edge of town two decades ago, enjoying relative anonymity while keeping horses.
Jones was just someone you'd run into at the post office, Wagner said.
Next-door neighbor Carol Wickard said Jones was a kind man who helped the community - once making a donation to keep the town's library open.
"When it was down, he helped this town," Wickard said.
Wickard said Jones would wear a wig to trim his hedges, even though fans would come by only once in a while.
"I'd say, 'Just don't open your mouth. You're the only person around with an English accent,'" Wickard said.
The concert is being organized by Wagner and Mike Shoenfelt, a fan from Altoona, who are arranging for a "jam fest" concert on the Firemen's Carnival Grounds followed by a service at the church Jones was rehabbing in hopes of building a Monkees museum.
A Facebook page for the event has more than 450 people promising to attend.
Wagner says he's a little worried about crowd control, even though it'll hardly be a rowdy event.
"This is a tidal wave," Wagner said. "Our population is going to double."
