On 27 February 1975, Harpo recorded the song for which he would become most famous - "Moviestar". One of the backing vocalists on that day was Anni-Frid Lyngstad (Frida) from ABBA. It has sometimes been reported that Agnetha Fältskog also sang on the song but this is incorrect. The second female singer is Lena Ericsson. Frida also provided backing vocals on the song "Pin Up Girl" on Harpo's second album, Harpo & Bananaband.
