The Lettermen Biography (from Yahoo!)
This very successful US close-harmony pop trio comprised Bob Engemann (b. 19 February 1936, Highland Park, Michigan, USA), Tony Butala (b. 20 November 1940, Sharon, Pennsylvania, USA), Jim Pike (b. 6 November 1938, St. Louis, Missouri, USA). Pike, a letterman at Utah's Brigham Young University, released an unsuccessful single on Warner Brothers Records in 1959. In 1960, he and fellow student and ex-Mormon missionary Engemann formed a trio with supper-club singer Butala, who had recorded previously on Topic and Lute.

After two unsuccessful singles, they joined Capitol Records and struck gold immediately with "The Way You Look Tonight". The smooth ballad singers put an impressive 24 albums in the US chart in the 60s, with 10 of them reaching the Top 40. The popular live act also had another 19 chart singles including the Top 10 hits "When I Fall In Love" in 1961 and the medley "Goin' Out Of My Head/Can't Take My Eyes Off You" in 1967. In 1968, Jim's brother Gary replaced Engemann and six years later their brother Donny replaced Jim.

In the 70s they were a top-earning club act and were much in demand for television commercial work. The group recorded on their own Alfa Omega label in 1979 and signed with Applause in 1982.
