The article says she was asked what song is commonly sung on midsummer's eve in Sweden. She became uncertain, so the embassy person started singing "Små grodorna" and she felt compelled to sing along. Nowhere in the article does it say she was forced, or even asked, to sing the song. Maybe she was, maybe she wasn't; the article only says she felt compelled.
