Haloo Helsinki! - Laula Lujempaa (Show Must Go On) link
At first I thought the title of the song was just a reference to the often-used phrase and not the song. However, lines such as "the power of this song is greater than a stadium" and "I wanna sing Queen in karaoke for the whole weekend" confirmed that they are indeed referencing the Queen song :D
The title of the song translates as "Sing Louder", so not getting the Queen reference right away was just sloppy logic by me. I was hoping she would sing the real melody to TSMGO in the last refrain, but it did not happen. Maybe they'll do it live if they ever perform this song.
I never thought/heard of these guys being Queen fans, but I guess you never know. Of course, TSMGO has been the most played Queen song on the radio for years and it's impossible to avoid it, even if you are not that much into Queen.
