The O'Kaysions are an American pop band, primarily known for their 1968 hit single, "Girl Watcher". Originating from North Carolina, their style fuses pop and blue-eyed soul, a genre typically associated with white artists who perform rhythm-and-blues and soul music. The band, initially named The Kays, achieved their most significant success in the late 1960s under the leadership of Donnie Weaver. Despite having a relatively short-lived peak, The O'Kaysions' signature sound left a lasting mark on the pop and soul music scene of the era.
