Prompt
"Generate an image of a 1960s Swedish folk music group performing on stage, with a nostalgic and retro vibe. The group, known as the Hootenanny Singers, should be depicted in their prime, with traditional Swedish folk instruments such as guitars, fiddles, and accordions. The style should be reminiscent of classic Swedish folk music, with a warm and cozy atmosphere. Include a subtle background hinting at their hometown of Västervik, Sweden. The image should evoke a sense of camaraderie and musical joy, capturing the essence of the Hootenanny Singers' contributions to Swedish folk and schlager music, and their role in launching the career of Björn Ulvaeus, later of ABBA."
