She did not want to sing karaoke, she was pretty clear about that. So the crowd (which is to say her sisters and cousins and family) let her be. Then, after a while, she got up and sang a wee bit of Sinatra.
That’s part of the spirit that has everyone remembering her and saying such wonderful things about her. She really was so young at heart. This was back in July this year, before a massive stroke incapacitated her.
