Harpers Bizarre was an American pop-rock band of the 1960s, best known for their Broadway/choirboy sound and their remake of Simon & Garfunkel's "The 59th Street Bridge Song (Feelin' Groovy)." Career Harpers Bizarre was formed out of The Tikis, a Californian band who enjoyed some local success with Beatle-like songs in the mid 1960s. In 1967, record producer Lenny Waronker got a hold of the Simon & Garfunkel song "The 59th Street Bridge Song (Feelin' Groovy)," determined to make it into a single.
