Hit Records was a record company based in Nashville Tennessee which from 1962-1969 specialized in sound alike or cover versions of popular hit records. Hit Records were sold for less than half the price of the hit recordings they were covering. The Cords were a band that work for the record label and did covers of some Herman Hermits songs as well as one from the Animals. The Cords did a fairly good version of The McCoys "Fever". I'm guessing that this 45 was released in late 1965 or early 1966. If you research the history of the bands who performed for Hit Records the Cords are listed as the Chords.
