The only thing the performer must watch out for is that the audience will soon tire of hearing everything in the same key. They will not know why it bothers them for the most part. They will just know that they don't like that. So make sure that you don't pull that one. All songs, all night, in Eb or any other one key is a drag.

Great advice and/or reminder for all performing musicians. I was given this advice (almost verbatim) from an old piano man when I was a mere youngster many years ago. I still do not understand the "audience why part" I only know it's true.
Just last week I was trying to explain this to a veteran reed man as I am helping him put together a one hour show. He loves to play in the key F (love) and while a one hour show might not be long enough for this "audience affect" to take place I sure don’t chance it.
Thanks for the reminder Mac!
