(Ocean Robbins) In 1970, the unheralded Swedish band Festfolket (“Party People” in English) made their television debut on a strange variety show called “Five Minute Saloon.” The quartet — Agnetha Fältskog, Björn Ulvaeus, Benny Andersson, and Anni-Frid Lyngstad — sang a frankly cringe-worthy rendition of “California Here We Come” (you can watch it here) while decked out in ridiculous Western wear. The reviews were largely negative, for this performance and also for their stage show.
