With regard to President Madison and Hail to the Chief, we have our own bit of fiction about that song in Canada. The myth goes that during WWII, FDR paid a call to Prime Minister MacKenzie King in Ottawa. Upon entering the room, the band struck up Hail to the Chief, causing FDR to ask King if the song was how the Canadian Prime Minister was officially greeted. King replied, no, nothing official, I just like it. FDR, upon returning to the US, had Congress sponsor a bill officially naming Hail as the offical song to be played whenever the president entered a function.
