An innocent song about teenage drug use and truancy. Itchycoo is slang for stinging nettle, an herb I swear by for pollen allergies.
The American Breed - Bend Me, Shape Me (1968) This band's only huge hit was a remake of the The Outsiders' song from year before.
The Osmonds -- Chilly Winds (1970) (No video, just this groovy pin-up.)
This song appeared in Pretty Maids All in a Row, an underrated creepy movie from 1970 written by Gene Roddenberry, directed by Roger Vadim, and starring Rock Hudson, who plays a high school football coach who rapes and murders the female students. If you want to watch it, you'll have to TiVo it, Torrent it, or buy a used VHS copy.
