I am pretty certain the vast majority wouldn't be interested tbh.
On a side note People seem to confuse the lack of perceived excitement at the Flute bands with not wanting or enjoying them, these nights normally it is a bit of respect to sit and watch the band play.
Personally getting a bit old for the flute bands myself, seen hundreds over the years, and its too loud indoors for me now
But ill never give up the loyalist tunes
The fact is , even if people don't like it, the very mast majority of the Rangers fan base and especially the ones who congregate in large numbers are very fond of both Loyalist music and culture and Flute Bands.
