Cricket sings the jazz standard "What's New?"; a song originally written as an instrumental by Bob Haggart in 1938. The addition of lyrics by Johnny Burke a year later resulted in a top ten hit for Bob Crosby and his Orchestra.
At approximately the 42 minute mark an uncredited and non-speaking Troy Donahue is seen on the beach kissing a girl then walks off as Shirley Knight's character sees them. Troy was previously the main character in this season's Episode 7 'Beach Boy' then went on to star in Season 4 as the social director at the Hawaiian Village Hotel after Anthony Eisley (Tracey Steele) left the series. It's very likely this was simply an outtake from "Beach Boy," used to establish the scene.
