His father, Milton Peek, says Dan Peek was found dead Sunday in bed in his home in Farmington, Mo., about 60 miles southwest of St. Louis. The cause of death isn’t yet known. An autopsy is planned.

Peek sang high harmonies for America on hits that included “A Horse With No Name” and “Ventura Highway.”

He had lived in Farmington since 1978, soon after leaving the band.

Peek was born in Florida. His dad was in the military, so the family moved frequently.

They were living in London in the late 1960s when Peek met singers Dewey Bunnell and Gerry Beckley. They eventually became the trio America.
