"whether it is a good thing or bad thing it is still stylistic restriction, it has nothing to do with the instrument but the performance."
NO IT IS NOT - it is an artistic decision to present one type of music rather than another.
It is no more a stylistic restriction that is the Royal Opera House not putting on Lady Gaga concerts - that is not the music they wish to promote.
It is certainly not a prejudice, most people love instrumental singing of one form or another - in its place.
The clubs here has decided that Irish traditional singing does not need accompaniment and has refused to have it imposed on their sessions - I go along with that and the sooner you stop singing "I'll sing it mY Way' the sooner you will understand that fact
