Time by The Pozo Seco Singers (1966)

Group members Don Williams (Gregory-Portland HS grad) and Lofton Kline were playing together under the name The Strangers Two in Corpus Christi, Texas when Susan Taylor aka Taylor Pie heard them at a Circle K hootenanny held at Del Mar College. She asked the two if they'd like to form a trio, which became the Pozo Seco Singers. Taylor, a student at W.B. Ray High School at the time and charter member of the local folk music society, introduced them to Paul Butts, their first manager. "Time" written by Michael Merchant was the group's first recording for a local label, Edmark Records and it was an instant regional hit. Columbia Records then signed the three and nationally released the song which became the title of their first album. Two more albums followed on Columbia, they signed with Albert Grossman management, and Kline was replaced by veteran folk singer Ron Shaw . Lofton Kline pursued a solo career after leaving the group and is currently recording Christian music. When the group disbanded in 1970, Taylor focused on songwriting for JMI Music and had songs recorded by artists such as Tanya Tucker, The Lewis Family, John Conlee, The Forester Sisters, and Mickey Gilley. Shaw joined the popular commercial folk group, The Hillside Singers and Williams went on to a highly successful solo career in country music.
