Corrected entry: Right after Sam, Bill, and Harry arrive and they are all in the goat house with Sophie, they hear Donna humming something, which prompts Sophie to run out abruptly. Listen more closely to what Donna's humming. It's "Fernando", another hit ABBA song.

Correction: The entire soundtrack to the film consists of ABBA songs. Pointing out one of them, even one less obvious that those that are actually sung, is not a valid use of trivia.
