Background: The Kingston Trio is an American folk and pop music group that helped launch the folk revival of the late 1950s to late 1960s. The group started as a San Francisco Bay Area nightclub act with an original lineup of Dave Guard, Bob Shane, and Nick Reynolds. It rose to international popularity, fueled by unprecedented sales of LP records, and helped to alter the direction of popular music in the U.S. The Kingston Trio was one of the most prominent groups of the era's pop-folk boom that started in 1958 with the release of their first album and its hit recording of "Tom Dooley", which sold over three million copies as a single.
Context: Following the Hungry i engagement, Reynolds moved to Port Orford, Oregon and pursued interests in ranching, business, and race cars for the next twenty years. Stewart commenced a long and distinguished career as a singer-songwriter, composing hit songs like "Daydream Believer" for The Monkees and "Runaway Train" for Rosanne Cash. He recorded more than 40 albums of his own, most notably the landmark California Bloodlines, and found chart success in the top forty with "Midnight Wind", "Lost Her in the Sun", and "Gold", the latter reaching number 5 in 1979. Bob Shane decided to stay in entertainment, and he experimented with solo work. He recorded several singles, including a well-received but under-marketed version of the song "Honey" that later became a million-seller for Bobby Goldsboro, and with different configurations with other folk-oriented performers. Though finances were not an immediate concern--the Kingston Trio partners Werber, Shane and Reynolds still owned an office building, a restaurant, other commercial real estate, and a variety of other lucrative investments--Shane wanted to return to a group environment and in 1969 secured permission from his partners to use the mutually owned group name for another band, with Reynolds and Werber insisting only that Shane's group be musically as accomplished as its predecessors and that Shane append "new" to the band's title. Shane agreed and organized two troupes under the name of "The New Kingston Trio". The first consisted of guitarist Pat Horine and banjoist Jim Connor in addition to Shane and lasted from 1969 to 1973, the second including guitarist Roger Gambill and banjoist Bill Zorn from 1973 until 1976. Shane tried to create a repertoire for these groups that included both the older and expected Kingston Trio standards like "Tom Dooley" and "M.T.A." but that would also feature more contemporary songs as well, including country and novelty tunes. The attempt did not meet with any significant success. The only full-length album released by either group was The World Needs a Melody in 1973 (though 25 years later FolkEra Records issued The Lost Masters 1969-1972, a compilation of previously unreleased tracks from the Shane-Horine-Connor years), and its sales were negligible. Though both troupes of the New Kingston Trio made a limited number of other recordings and several television appearances, neither generated very much interest from fans or the public at large.
