Benny Anderssons Orkester (BAO!) started out by performing "Du är min man" followed by a brief interview by host Anders Lundin with Benny and Helen Sjöholm.
Then there was the sing-a-long, which was "Augustin" (Sweden’s entry in the 1959 Eurovision Song Contest), led by Helen and with BAO! providing backing.
BAO! came back later in the show, performing "Sommaren är här" (The Summer Is Here), with Tommy Körberg on vocals and then he was also interviewed by Anders Lundin.
Then there was the second sing-a-long, which was "Säg det i toner", led by Tommy and with BAO! providing backing.
