Song For Guy by Elton John is an instrumental piece with a few lines of lyrics towards the end. The song is a tribute to Guy Burchett, a young messenger for Elton John's music label, who tragically died in a motorcycle accident. The primary theme of the song is mourning and loss, presented through a haunting and reflective melody. The repeating line 'Life isn't everything' poignantly encapsulates the fragile and transient nature of life. The minimalist lyrics and melancholic piano arrangement evoke a sense of deep contemplation and sorrow, making it a heartfelt homage to the memory of a lost friend.
