The practice however spilled over into the 'concert' flutes: there's the wellknown story of the Tulla ceiliband going for audition to appear on the radio during the late 40s/early 50s where one of the fluteplayers ran water through the flutes and the whole thing went pear shaped. the band didn't appear on radio for another twenty years.while this is a pretty bad practice if you actually want to keep your flute in good condition, the improvised and impermanent nature of the instrument meant that the damage didn't really matter.
In a Micho Russell related context: I have done some leg work in Clare with regard to photographs for the late Bill Ochs' book on Micho, one absolutely wonderful 1920s or so original print of the Kilfenora fifeband came through my hands for scanning. Wonderful stuff, the past is indeed a country where they did things differently.There were many fife and drum bands at the time
Apologies for going off topic, by the way.
