[2] According to a critic at Vecko-journalen (The Weekly Journal), Hedberg was "a sweet-sounding soprano with an echo of the rural forests, mountains, waterfalls and cow bells in her voice.

While on her longest tour she gave 50 concert performances in 81 days, acquainting audiences with the latest songs and stories from Sweden.

She found "repeated proof that my singing softened their American hearts, whose very fibers must be moved by verses about the poor countryside at home in order that their true Swedish feelings might emerge.

"[7] The Centre for Swedish Folk Music and Jazz Research had two Hedberg recordings on its album “From Sweden To America”, which was released as an LP in 1981 and as a CD in 1996.

The Swedish-American singer Olga Lindgren-Nilsen, who was married to Olle i Skratthult in the 1920s, gave credit to Hedberg, Fonandern and other performers from Sweden for providing much of her new material.
