What song is this - Bergen music fest 2023?

Hi, I think this is Norwegian... I was in Bergen for my honeymoon in June 2023. Unbeknownst to us, the Bergen Music Festival was happening and we heard this fun song being played live on a boat. Can anyone tell me if this is Norwegian and if so, what some of the words are? This might help me ID the song / artist. Thanks!
