20 June 2019 | By The Associated Press Jim Pike, a co-founder and the lead singer of the Lettermen, a trio whose lush vocal harmonies made them one of the most popular vocal groups of the 1960s, died on June 9 at his home in Prescott, Ariz. He was 82. His sister-in-law Becky Pike confirmed the death to The Associated Press on Wednesday. The cause was complications of Parkinson’s disease. Mr. Pike and Bob Engemann, a college friend from Brigham Young University in Provo, Utah, formed the Lettermen in Los Angeles in 1961 with a fellow singer, Tony Butala. They were looking for a name that would resonate with young people when Mr. Engemann suggested the Lettermen, Mr. Pike’s younger brother, Gary, said on Wednesday. Mr. Butala had briefly sung with a group known as the Lettermen and got its leader’s permission to use the name, Gary Pike said. .
