In regards to the "blue book" or "RUS" (Rise Up Singing) - I have never seen one appear at our jams, although I do have a copy sitting on my shelf. In fact, I doubt many people in my circle even know that book exists, thank goodness.

What I do see being used more and more, by the people in our group who must work from cheat sheets, is reams of computer print outs. The internet has contributed greatly to people being able to find nearly any song they want within seconds. Both a blessing and a curse !
