The flexible, indeed slippery vocalistEddie Hall was a member of the Kirby Stone Four, a highly original vocal group that cut several albums in the late '50s and early '60s. Besides Hall and leader Stone, the other members of the quartet were Larry Foster and Mike Gardner. The group was known for a so-called "hip" style of joking which was combined with a low-key but swinging musical style in which uptempo rhythms dominated. The Kirby Stone Four became a hit as a vocal foursome, but actually started out in a more normal instrumental combo. The novelty of leaving the instruments at home helped the group succeed, since it immediately eliminated quite a bit of competition. Great talent is needed to pull off such a musical venture, however, as good tone and delivery come much less easily out of human vocal chords than a plugged-in bass or a piano keyboard, especially when neither is available to provide accompaniment or fill in the holes. Hall and his partners seemed to be judged as having what it takes, as the group rose from steady nightclub engagements and local television appearances to a 1958 triumph on the Ed Sullivan Show.
