The Monkees were the made-for-American-TV group that attacked video and audio airwaves in 1966 at the height of Beatlemania. The NBC series aired only two seasons but won the 1967 Emmy for Outstanding Comedy Series and also launched the group to radio stardom. Their first hit was "Last Train to Clarksville," which started a run of five consecutive Top 3 singles stateside. The song also was the first of three chart-toppers followed by "I'm a Believer" — which also hit No. 1 in the UK — and "Daydream Believer."
