I remember as a kid watching this commercial on TV (translated of course). Years later I realised that the father of this famous composer was actually a brewer. This commercial made an impact due to that the company of this beer made a very good reference to the father, the composer, the song about fatherland which reflects in the crowd coming together, and the flowing river (song) which reflects the beer. The beer comes from Czech Republic as well.
