Sweden is the red-hot favourite for this year's Eurovision Song Contest on Saturday in the Swiss city of Basel, with an offbeat song about saunas which could cool some recent controversies at the show.

KAJ, a Finnish trio, will represent Sweden in the annual contest with their song, “Bara Bada Bastu,” a catchy ode to sweating out one's stresses.

Finnish politicians have long used saunas, relaxed but exposing, as an ideal setting for hard talks, a practice known as “sauna diplomacy.” KAJ wear drab suits onstage in tribute to Urho Kekkonen, a long-serving Finnish president who famously deployed the technique in talks with Finland’s overbearing neighbor the Soviet Union.
