"What Have You Done" by Gerry Cinnamon is a song that explores themes of disillusionment, self-destruction, and the consequences of one's actions. The song starts by addressing someone, possibly a son, who has made regrettable choices in their life. The lyric "What have you done son/Sold your soul to the demon" suggests that the person has made a deal with the devil or compromised their morals for personal gain. The line "Dance like a dafty for a bag of snow" metaphorically portrays the person engaging in reckless behavior, possibly involving drugs, for temporary pleasure or escape. The phrase "bag of snow" is a colloquial term for cocaine. The question "Where will you run son when the joke gets old?" implies that the person's actions will eventually catch up with them, and they will have nowhere to hide or escape from the consequences of their choices. The song then shifts to the perspective of the singer, who finds themselves surrounded by strangers, feeling out of place in a disoriented world. The line "Messed up circle in a room of squares" suggests a sense of not fitting in or feeling disconnected from society. Despite this feeling of detachment, the singer continues to dream of a world without nightmares, symbolizing a desire for a better, more positive reality. However, the lyric "But what do you care?" implies that no one else seems to share or care about this dream, possibly reflecting the apathy or indifference of people in general. The repeated phrases "La-di-da-da, la-la-la-la-la-la" and "Da-da-da-da, la-di-da-da-da" act as a rhythmic and melodic element, and while they don't have a specific meaning within the song's narrative, they add to the overall emotion and tone of the song.
