I'm with Joe - ANY printed book (or even the Digitrad) could be misused in the ways described above and previously. Fortunately, no 'Catters have started whining "That's not the version in the DT".In a group of - for lack of a better term - experienced musicians or singers, who can follow whichever version of a song the leader happens to be doing, GREAT! But when you have a room full of people who go to a sing-along twice a year, it really helps to have a guide. The group I'm with feels free to "challenge" RUS, and my copy has so many additions and changes written in the margins it's even harder to read than the way it was printed (which is MY biggest beef with the book)
IMHO, its still the best "guidebook" - with the most "suggestions" in one compact place.
