Toni Wine was 17 when she co-wrote this song, which was a huge hit for The Mindbenders in 1966, followed by others.
In an interview with songfacts.com, Toni Wine explained: "We were talking about 'Groovy' being the new word. The only song we knew of was 59th Street Bridge Song, Paul Simon and Art Garfunkel. You know, 'Feelin' groovy.' And we knew we wanted to write a song with that word in it. Because we knew it was the happening word, and we wanted to jump on that."
