We have done lots of bookings (paid & unpaid) in nursing homes and always enjoyed them. I agree that its important to involve the audience as much as possible and we usually get a few requests. Its amazing how much people will join in and contribute. I always make sure that the staff are aware of the sort of programme we do and we often find that the staff enjoy it just as much
I quote one elderly gentleman "That was my wife's favourite song, will you do it again" This from a person who the staff said hardly ever spoke or communicated with the others. Very rewarding. Percussion instruments handed out by the staff always lend to the afternoon.
