Benny and Orsa Spelmän perform "Machopolska" and "Stjuls" live during "Flyktinggalan" ("Gala for Refugees"), a charity event where viewers were asked to call a phone number and donate money.
(I'm assuming it's Flykting Gala as it's the same presenter and obviously a charity programme - I could be wrong however - please correct me if so!)
The presenter was Kjell Lönnå.
