The song "Animal Kingdom" by Catherine Bennett talks about the different dynamics of relationships and friendships. The lyrics discuss how friendships are like flocks of birds, moving together through life, and how some friendships are for different reasons and seasons. It also touches on the bond between sisters, comparing them to swimming in the sea, tied to each other inexplicably. The chorus emphasizes the idea of being alive and well in the animal kingdom, thriving and sailing on the friendship. The bridge, performed by Jon Burgerman, further emphasizes the theme of sailing on the friendship through calm and rough times, and describes friendship as love. The song also addresses the idea of enemies living in arid lands, with dust in their throats and blood on their hands. It suggests that instead of being enemies, we should hold hands and befriend each other. Overall, the song "Animal Kingdom" is about the different relationships we have in our lives, from friendships to family, and the importance of love and friendship in navigating through life's challenges.
