Debbie Watson is the ideal perky teenager of the 1960s, who started when she became one of the hopefuls of Ted Mack & the Original Amateur Hour (1948) in 1963 and, the following year, she starred as "Karen Scott" in Karen (1964) on "90 Bristol Court" (1964) and, after that, she's the 3rd and last actress to play "Tammy Tarleton" on Tammy (1965). Both of her TV shows lasted 1 Season, each, by Universal Pictures Television (and now NBC Universal). In 1967, the movies, The Cool Ones (1967) & Tammy and the Millionaire (1967) were flops of the year and continued appearing on television until her retirement in 1972.
