Last Saturday before the match against Stuttgart, there were three brass bands playing Bavarian tunes as part of the pre-match programme and at one point the Stuttgart supporters started whistling. Then the Südkurve started singing a hymn with music similar to 'I am sailing' and there were words like 'kein schwaben'. It doesn't seem to be new since it seemed popular with the other supporters as well.
Does anybody know what this hymn is called ?
Thanks
