I'd rather go to a pub or session and see folk singing live from a book or crib sheet then have no music at all. Come on live and let live.
There are places in the world where getting together for a sing around or to see live performers is still prohibited.

So if some of you have to get high and mighty about what should or shouldn't be aloud make it something worth having a grumble about.

In the meantime Chris use yer book where and when you like.
