If you listened to the radio in the 70's and early 80s you heard Olivia Newton-John. You also heard the iconic band ABBA and the youngest of the Gibb brothers (known as the Bee Gees), Andy Gibb who had his own solo career.
This is rare video, tremendous sound, and no lip synching! Crank up the volume (or put on some headphones). and enjoy vintage Olvia Newton-John, ABBA, and Andy Gibb.
