I must be the odd one out. I always enjoy it if the singer introduces the song and explains its significance to him or her, and how they come upon the song.

I also think if you want other people to join in with their instruments you should tell the company what key you are going to try and sing and play in.

after all we are 'folks'. our relationship with each other is not a 'given'. if you wish to astonish the world with a tour deforce that will amaze and mystify -fuck off into the desert and sing to the cacti.
