In the 20's a good home in America were supposed to have a piano and a C (-melody) sax. The C saxplayer could read over the pianoplayers shoulder. I've done that a lot. My wife on piano, singing as well, and I played C sax. I played the singing/melody line without tranposing. We played Swedish folkmusic. I rember Birger Sjöberg was often played and. A nice way to spend an evening. This was before internet (Breakfastroom, SOTW, YouTube, MySpace ...) got into my life.
