Yeah, Peace: I think there is a great deal to be learned (and received) stepping out of our "comfort zone" as a performer and playing to an audience unfamiliar with our music. It sounds like you understood and respected your audience, and when that is the case, the individual song almost becomes unimportant. When my wife and I do a monthly program at a nursing home, sometimes I think that just holding someone's hand is at least as important as singing them a song. They definitely would relate to I Want To Hold Your Hand.
Touching is so very important for them. The only time they're touched may be when their bed linen is changed or they're helped into their wheelchair. Holding hands is a sign of affection, and it is very different.
