Peter Piper - Whats The Good Word, Mr Bluebird Lyrics

What's the good word, Mr. Bluebird?
Did you bring a song to cheer me up today?
Give me your word, Mr. Bluebird,
Did you come to tell me everything's okay?
I've been blue, because there was no letter;
Seeing you has made me feel much better,
What's the good word, Mr. Bluebird,
Before you fly away?
