If you ever listen to the BBC World Service, Liliburlero is still the station signature tune. There's a lovely video clip they use for promioting the BBC with the Dalai Lama humminmg it appreciatively.

Less charming are the words of "The Protestant Boys", which go with it in Orange circles in Northern Ireland and Scotland -
"Slitter slaughter, holy water, scatter the Papishes every one
If that won't do, we'll cut them in two and send them to Hell, with the Orange and Blue" and so forth. So there are situations where you need to be careful with this tune, or you might get misunderstood.

Nationalism and folk music can be a dangerous mcombination.(And at the same time it's an example of how a good tune can move between enemies. Like that other Lili, Marlene.)
