"A Love So" is a song by Gilbert O'Sullivan that explores the theme of love and affection. The lyrics describe the different ways in which the singer experiences love and the impact it has on their life. The song starts by expressing the joy the singer feels when they receive love and affection in the morning and at night. They appreciate the little gestures of love and want to be liked by their partner. The love they share is described as true and pure. The lyrics further reveal that the singer has never needed anyone in their life before, but now they have found someone who makes them feel wanted and loved. They have a newfound longing for affection and enjoy the feeling of being held and cuddled by their partner. This love is described as rare and special. The song then takes a different turn as it touches on the idea of commitment. The singer talks about signing a paper, symbolizing their commitment to stand together with their partner. They understand that there may be occasions where their explanations might not make sense, but they are willing to overcome any challenges that may come in their relationship. The lyrics also suggest that the singer had doubts about their abilities and love until they tried and experienced it. Love and affection were unknown concepts to them, but now they appreciate and enjoy these feelings. The love they have found is something they cherish and consider to be great or extraordinary. Towards the end of the song, there is a mention of being on cloud nine, a reference to the happiness and contentment that love brings. However, it is juxtaposed with the idea that even in the midst of such happiness, external factors like societal expectations or restrictions (depicted as a prison yard with guards) can limit one's freedom. Overall, "A Love So" is a heartfelt song that portrays the transformative power of love and the joy it brings to the singer's life. It conveys the importance of affection and appreciation in a relationship and the willingness to overcome challenges for the sake of love.
