I'm Seeing Blue

What is it about blue? My Blue Heaven, Blue Velvet,  Blue Suede Shoes, Am I Blue, Blue Skies,and other songs titles ad infinitum. And that's not even counting the patriotic songs or  the use of 'Blues' as a genre.It's a favorite color for a vast number people. And between the sky and the seas, it's a universal background to life.So I bring you the April tribute to Blue, Vintage style.
