LEWISTON —  It’s a little “home of the free” meets “Crazy Train.”

The headliners at Sunday’s 2010 Liberty Festival: the big-haired, full swagger ’80s metal cover band, Twyce Shy.

They’ve got the wigs, the tight pants, the stage names, the invented back story and Lewiston High grad Class of ’91 Jerry Perron on guitar.

“We get all done up and all the music is from that era,” said Perron, who owns The Music Center in Brunswick. He’s also in the bands “Hey Buddy” and “Punch Bug.”

Twyce Shy started, he said, when the other guys, all customers at his store, wanted to play together about three years ago. They booked one show — “It was supposed to be a joke, it was supposed to be a one-time thing” — and the show sold out. They’ve kept it up since.

They cover bands like Guns’n Roses, Ratt, Poison, Van Halen, Bon Jovi and Ozzy. The back story? Rod Steele (Mark Courturier, lead vocals), JP Marino (Perron, guitar/vocals), Rycky Styx (Rick Lewis, drums/vocals), DeeZul (Darren Milliken, guitar/vocals) and Blackie Richmore (Fareen Pelkey, bass/vocals) were on their way to a UK Monsters of Rock show in 1987 when their plane went down. Decades later, rescued by a lobsterman, they’re back.

“We play Club Texas once and a while, 400 to 600 people come out,” Perron said.

Richard Martin, president of the Independence Day Committee, which puts on the Liberty Festival, said they pulled the night’s entertainment together in about three weeks. The first band taking the stage: Jeroba Jump, an ’80s rock band from Maine.

“We were fortunate in that L-A Music Factory, which puts on sound for us, does sound for both of those bands,” Martin said.

The concerts in Lewiston’s Veterans Park are free. The evening starts there with the national anthem at 5:30 p.m.

Across the river, the Hilton Garden Inn is hosting the sixth annual Hilton Party with music by “Veggies By Day.” Those tickets are $15 apiece.

New this year, Martin said, will be fireworks by Central Maine Pyrotechnics out of Hallowell, touching off at 9:30 p.m. by the falls.

“They seem quite promising,” he said.

July 5 will be the rain date for fireworks, but not for entertainment and vendors.

Roughly 20,000 to 30,000 people turn out to see the display each year, he said. Just on Longley Bridge, “You might have 2,000 to 5,000.”

Martin said the Independence Day Committee is still looking for support for this festival and future ones. For more details, www.libertyfestival.org
