Mr. Peek, who sang lead and backup vocals, also played guitar, bass, keyboards and harmonica. The band’s best-known songs during his tenure include its two biggest hits, “A Horse with No Name” and “Ventura Highway,” both written by Mr. Bunnell; “Sister Golden Hair,” by Mr. Beckley; and “Lonely People,” by Mr. Peek. Mr. Peek also wrote “Woman Tonight” and “Don’t Cross the River” for the band. After leaving America in 1977, Mr. Peek recorded Christian pop, including the successful solo album “All Things Are Possible,” released in 1979. In recent years, he lived in somewhat reclusive semi-retirement while continuing to write songs. Daniel Milton Peek was born in Panama City, Fla., on Nov. 1, 1950. His father was an Air Force officer, and Dan spent his childhood all over the United States, and in Greenland, Japan and Pakistan. When he was a teenager, a new posting took the family to England. It was there, in a London high school, that he met the young Mr. Beckley and Mr. Bunnell, also children of American military fathers. The three began singing together in various permutations, under various names. They dissolved briefly when Mr. Peek returned to the United States to attend Old Dominion University, but joined forces again when he came back to London a year later. They called themselves, nostalgically, America. “We wanted to set ourselves apart and not be seen as English guys trying to do American music, but instead accentuate that we were an American band,” Mr. Peek told The Jerusalem Post last year. The group’s self-titled debut album was released in Britain in 1971 and in the United States by Warner Brothers the next year. The band won a Grammy Award in 1973 as best new artist. A string of successful albums followed, including “Homecoming,” “Holiday,” “Hearts” and “Hideaway.” Many were produced by George Martin, who produced many of the Beatles’ records. As Mr. Peek later recalled, those early years passed in a blur of airplanes and limousines, wealth, drugs and alcohol. “Sex, drugs and rock ’n’ roll; it was the whole cornucopia of fleshly material,” he said in an interview with the Christian Broadcasting Network show “The 700 Club.” “I tried everything. I tasted every possible thing. I had a spiritual compass, but I abandoned it completely.” In 1977, distraught at the turn his life had taken, Mr. Peek became a born-again Christian. He renounced drugs and alcohol and left the band. He signed with Lamb & Lion Records, a label founded by Pat Boone, for which he recorded “All Things Are Possible.” His other albums of religious music include “Electro Voice,” “Cross Over” and “Caribbean Christmas.” (Mr. Peek and his wife lived in the Cayman Islands for many years.) Mr. Peek is survived by his wife, the former Catherine Maberry, whom he married in 1973 (he met her, too, during his high school days in London); his parents, Milton and Gerri; and five siblings, Tom, Deborah, Rebecca, David and Angela. Since Mr. Peek’s departure America has been principally a duo comprising Mr. Beckley and Mr. Bunnell, and it continues to tour. “We’ve had innumerable requests to re-form, but the ball’s in their court,” Mr. Peek said in The Jerusalem Post interview last year. “I would probably do it.” A version of this articles.
