Im A Believer Video (MV)

"I'm a Believer" is a song written by Neil Diamond and recorded by American band the Monkees in 1966 with the lead vocals by Micky Dolenz. The single, produced by Jeff Barry, hit the number-one spot on the U.S. Billboard Hot 100 chart for the week ending December 31, 1966, and remained there for seven weeks becoming the last number-one hit of 1966 and the biggest-selling single for all of 1967. Billboard ranked the record as the number-five song for 1967. While originally published by Screen Gems-Columbia Music (BMI), it is now published by Stonebridge Music/EMI Foray Music (SESAC), with administration passed to Sony Music Publishing and Universal Music Publishing Group.

The song topped the UK Singles Chart for four weeks in January and February 1967. Also, it reached number one in several other countries, including Australia, New Zealand, Canada, and Ireland.

Billboard described the song as "an easy-go dance mover" that "will hit with immediate impact". Cash Box said the single is a "medium-paced rocker [that] is full of the group's top-notch harmonies and is laced with infectious sounds." Record World said it was "sensational."

The song was featured in four consecutive episodes of the television series The Monkees in December 1966. The members of the Monkees later performed it live during domestic and overseas tours at that time and many years later at reunion concerts.
