It'll never work in nursing homes. Are you crazy??? Pure audio-video-musical heaven. Spend a day collecting information about the residents. Scan some family pictures. Get shots of the neighboring countryside or whatever. Sing "I Left My Heart..." and have a quick slide show of SanFran. Have a live cam on-hand. Show them singing and having a good time. Save the recording (or make a separate recording of your set) and let the NH play it during the week. Do you think you won't be the most popular guy there? You'll be asked back immediately.

Playing that retirement party, the kid's birthday party, a 50th wedding anniversary? This is a winning concept. Who wants to be the first one on the block to try this? I don't think it will be me, but one of you can do this.
