Since its launch by inventior Ruth Handler in 1959, the Barbie doll (and her fictional universe) was a pop culture behemoth that spawned inumerable accessories and merchandise.
In 1961, Mattel released a 45 RPM record in which Barbie, performed by Charlotte Austin, and Ken, performed by Bill Cunningham, sang six songs with a swing style common to the late 50s and early 60s. It came with a booklet that I gather had the lyrics. They describe an idealized vision of romance suitable for young audiences.
The album is available on YouTube. You can also purchase a copy from eBay.
