Carry on! - doing the blues

I planned to produced a true blues song of my own since already longer! Now, this is the result of my efforts I undertook only this week! The story seems to be indeed a little bit sad on the first look (like all blues songs, therefore we call them some "blues"), yet on the other hand not so very clear, too, because of the singer`s good old friends who just take him to the boulevards and pay for his drinks there after his true love has left him only a short time ago quite obviously!
