I have to admit that, apart from their splendid Fairytale of New York, I don't know very much of the Pogues.
Perhaps I should make an effort.
I do remember that Irish bands such as The Dubliners, whom I saw live while at university, were at the heart of the 1960s 'folk revival'.
As for hearing authentic native music while on holiday in whatever country, it's important to get away from the tourist bars and music lounges.
In Thailand, for example, in Bangkok and the (in)famous seaside resorts such as Pattaya and Phuket, there are lots of Thai bands playing 'Western' music for tourists. They nearly all have the same repertoire - a few very familiar Beatles, Eric Clapton and Eagles songs, played on three guitar chords and with badly pronounced lyrics.
If you wanted to hear authentic Thai music, it's not too hard to find, but you would have to go elsewhere.
I suspect the same is true of most tourist destinations.
Listen to Spanish music in Ibiza? Forget it!
