Her musicians on this cut are listed as "Her Novelty Orchestra", but actually it is only a violin and piano.  This song is along the same line as the "Tiptoe through the tulips" number.  Lover is overwhelmed with love for another but cannot tell them that they love them so they go out into the park to tell the tulips or the daffodils or the blackbirds or the bluebirds.  Basically, anything that will listen to them!  It seems to be comon theme in the 1920's at least for the songwriters of the time to take a walk when you are in love and contemplate with the flowers and birdies!  The songwriting on this number is somewhat dated and disjointed but in a testament to her singing Annette carries it off quite well.  Her presentation makes the number.
