This is a great little video sent to me via my husband's grandma. She is 90-years- young and we have amazing similar taste in things, which I am unabashedly proud of.
Here is part of the Rat Pack: Sammy Davis Jr., Frank Sinatra (Ol' Blue Eyes), Dean Martin and a very young Johnny Carson (People, I remembered their names off the top of my head, no Googling for me!:) singing together. Enjoy!
