When we interpret the meaning being expressed, the lyrics of 'Shotgun Blues' by Bob Campbell show the singer's protective and possessive feelings towards their partner through metaphors which compare their partner's safety to shooting a deer killer. The couple's separation is shown through moonlight and the partner's invisible state while the relationship's boundaries are established by the partner's warning against outside interference. The lyrics of Shotgun Blues show love and angst and anger and heartbreak and nature as their main focus. The song conveys two main themes which are loss and yearning and violent revenge and self-reflection and despair. The lyrics contain themes of violence and references to firearms which may not be suitable for younger children. The content stops short of reaching the intensity and explicitness that would need a higher rating.
