“Tree Of Love” was inspired by the song of the same name written by Mark “Cal” Callaghan and recorded by GANGgajang on the 1987 album GANGagain. It proved to be a popular song in Brazil where it’s sung as “árvore do amor”. I have thought that perhaps the tree is in fact the “tree of infatuation”, covered as it is in glittering and glistening diversions, and the Tree Of Love is in fact the old oak tree behind the little door in the back panel. 

The lyric quoted in the painting is..."Every saint and every sinner, As they paw the desert sand, For the fruit that falls each night, From the Tree Of Love".
