On 3 September 1967, Anni-Frid "Frida" Lyngstad won the national Swedish song contest "New Faces", arranged by record company EMI and held at Skansen, Stockholm.

She spent five years at EMI Sweden before switching to the Polar Music label and joining Benny Andersson, Björn Ulvaeus, and Agnetha Fältskog to form ABBA in 1972.

The live version of "Barnen sover", (The Children Are Sleeping) was recorded on 29 September 1970 for the radio show, Våra favoriter (Our Favourites).

This was the very first public appearance of Anni-Frid Lyngstad, Agnetha Fältskog, Björn Ulvaeus and Benny Andersson as a quartet, shortly before their 'Festfolket' tour.

Writing for AllMusic, Bruce Eder lauded the compilation album and observed that Anni-Frid Lyngstad was set up to be "Sweden's answer to Petula Clark" by her management, and deemed the earlier, "thicker" music production a poor fit; however, Eder was more favourable to Benny Andersson's "airy and open, light-textured yet distinctive" production works with Lyngstad.
