Tea For The Tillerman by Cat Stevens is a reflective and poignant song that delves into themes of innocence, growth, and the passage of time. The song contemplates the changes that come with aging and the loss of childlike wonder. It speaks of a desire to return to simpler times and cherish the small joys in life. A particularly poignant moment is the line 'Oh, Lord, how they play and play for that happy day,' which underscores a longing for happiness and the purity of childhood.
