What is the relation between the last season of La Casa de Papel and the biggest Portuguese rock band?

Let’s start with the Portuguese idea of “saudade”, missing someone or something.
And how it relates to a traditional Portuguese song from the 50’s called “A Minha Casinha”.

"A minha casinha" is also one of the biggest hits from the rock band “Xutos & Pontapés”, a theme so popular that it became an anthem for the Portuguese people. The lyrics talk about “saudade”, but also of the joy of living in a modest apartment. The film shows the band returning to La Casa inside a military helicopter. The path is totally based on one of the last scenes of the fourth season. It’s the “saudade” that makes us want to return home, to our own “Casa de Papel.” And this is the most emotional way to connect portuguese people intimately with the series.
