Here are two performers that really enjoyed performing together. Dean was used to working with a partner (Jerry Lewis) but Frank wasn't - this led to some very funny ad-libbed moments. Everything Frank and Dean did together had a spontaneous feel; they didn't need rehearsals... so they didn't. With decades performing before live audiences they were prepared for anything. Sammy Davis Jr. makes a surprise appearance as well—doing his Amos 'n' Andy impression which, in hindsight, isn't terribly PC.
Also a part of this family show are Frank's kids Nancy, Tina, and Frank Jr. along with Dean's offspring Claudia, Craig, Dean Jr, Deana, Gail, Gina, Ricci, and Mrs. Martin. The highlights are tunes crooned by Dean and Frank, separately and together.
