The band Kiss shed the make-up and pulled out acoustic guitars to raise money for the renovation of the Oregon Military Museum.
The Oregonian reports the $2,500-(Dh9,182)-a-ticket gala on Sunday night in Lake Oswego raised more than $1 million.
The museum is named for the father of lead guitarist Tommy Thayer. He is Brigadier General James B. Thayer, now 93, a World War II hero who liberated a Nazi death camp.
The museum is at the Oregon National Guard’s Camp Withycombe in Clackamas. The renovation is expected to cost $15 million, and half has been raised.
An auction on Sunday included one of Kiss member Paul Stanley’s guitars, fetching $20,000.
The paper reported the band did a 14-song set, closing with an unplugged version of Rock and Roll All Nite.
