Oriole Four

The real beginning of the Oriole Four, 1970 International champion quartet, was in 1951 outside a Baltimore high school - although no one, of course, knew it at the time. That's when students Fred King and Jim Grant first met, discovered they had a mutual fondness for harmony and sang an impromptu duet. They joined the Society a couple of years later, found two other students who liked to harmonize and formed the Deacon Four, with Jim on lead and Fred on baritone. The quartet, with occasional personnel changes, was still getting together now and then after its members had graduated, and in 1956 the name was changed to the Oriole Four.

Orioles

This highly influential vocal group was formed in 1948 in Baltimore, Maryland, USA. Along with the Ravens, the Orioles were considered the pioneers of rhythm and blues vocal harmony. The group members were Sonny Til (b. Earlington Carl Tilghman, 18 August 1928, Baltimore, Maryland, USA, d. 9 December 1981, USA; lead), Alexander Sharp (b. 1919, Baltimore, Maryland, USA, d. 1970; tenor), George Nelson (b. Baltimore, Maryland, USA, d. 1959; baritone), Johnny Reed (b. 16 July 1923, Baltimore, Maryland, USA, d. 18 June 2005, Lakewood, New Jersey, USA; bass) and guitarist/second tenor Tommy Gaither (b. Baltimore, Maryland, USA, d. 5 November 1950, USA). Originally known as the Vibra-Naires, the group (with original bass vocalist Richard Williams) made their debut on the Manor label in March 1948 with the track "Tell Me So". The newly renamed Orioles (to honour the state bird of Maryland) launched their career with the quiet, languorous ballad "It's Too Soon To Know", which went to number 1 in the R&B charts (number 13 pop) in late 1948. The song was written by Deborah Chessler, the group's manager, and she wrote many of their subsequent hits.

Orphans

In 1950 a barbershop quartet, as yet unnamed, was to do a show in Wichita and the SPEBSQSA chapter president needed a name for the program, so he called the group 'The Orphans.' The name grew on them, and in 1954 they won District and Prelim contests, and then they were off to the Big Dance in Washington, DC.

Orrville Community Chorus

The vision for what has become the annual tradition of the Orrville Community Chorus began with one man, Victor Gerber. Victor (Vic) first performed "Messiah" in 1928 at Bluffton College, playing viola in a concert featuring a 200-voice choir accompanied by orchestra. In a 1993 interview Vic said, "I fell in love with the work and asked my minister, The Rev. A.R. Kaiser, if it could be sung in my home congregation at Salem Mennonite." The minister agreed. In 1932, Vic directed performances of Handel's "Messiah" at Salem Mennonite Church near Kidron and the First Presbyterian Church in Dalton. Corrine Gerber Krehbiel, Vic's sister, was the first piano accompanist. Thus began a tradition that continues to this day.
