Hi,
Seen a lot of this over the years and in various countries.
In Portugal, during the dictator days, there would be a lot of guitar folks asking for money in every corner and many of them would wait for the police to go around the corner and then switch songs to anything that was ... you got it! It was almost like clockwork, and even Luis Bunuel made fun of it in "Le Phantome de la Liberte" (The phantom of liberty), and I imagine that this was also popular in Spain during their Civil War.
In Brazil, there is a very large and successful amount of popular/folk music that is stronger in some areas and not in others. But in 1963/1964 (can I rmember that far?) Maria Betania belted out a vicious song ... "Carcara" ... and I was surprised that they did not thrown her in jail forever. The song had historical connections, so, its appearance was "safer" in some ways.
And then coming to America, it was hilarious and funny, hearing my first album in America on October 16th, 1965 ... Blonde on Blonde ... and the sarcasm, was insane ... you didn't have to know the lyrics to get it.
In Germany, on Guru Guru's "Tango Fango" album there is a satire about the music in the Eastern Block, and in some ways, the end kinda said ... rock'n'roll is out idol/god! Not many folks can even listen to that as it is very weird but it is hilarious. Let me play for you la bouchokaya! It kinda made a joke that the music on the East side of the wall was street marching band music, where as on this side of the wall, we had REAL MUSIC. GG was known to be at a lot of political things, but Mani always stuck to the fun side of it, and the like and you can check Daggelbert's Birthday (spelling) on "Dance of the Flames" to get an idea, but even then, he is already taking on greed and consumerism, so something about the music business had already changed and corrupted the German scene. (well known via AshRa/Klaus Schulze and such).
