Jethro has forsaken such earlier career goals as brain surgeon and double-naught spy: now, he aspires to be an astronaut. Meanwhile, bank secretary Jane Hathaway likewise decides to change careers, becoming a folk singer. Eventually, it is Jethro who takes up singing as a profession. Originally scheduled to air on March 23, 1966, "The Folk Singers" was rescheduled to March 30 due to CBS' coverage of Gemini VIII's emergency splash-down. ~ Hal Erickson, Rovi
