Dick,
Whether or not the objections were valid ones is a matter of opinion and the subject of much debate (to the great annoyance of the reviewer).
The review may not have been aimed directly at Mrs Cronin, but she, and others, became what is now referred to as 'collateral damage'.
The fact that it was one of at least four similarly bilious reviews which were (probably coincidentally) all aimed at Irish publications led some people here to think that there was another agenda in play.
None of these did traditional music nor Musical Traditions any favours; as for the reputations of the two reviewers - they have now become by-words for such reviewing - in Ireland anyway.
Hopefully we have seen the back of such behaviour.
