Danny, you may be right. I don't think Morrissey needs to explain beyond what he already said, but some kind of public appearance might not be a bad idea. If it were up to me, I'd put him on television doing one of the new songs, with the emphasis on the tour. Rather than spend too much time on NME a short dismissive comment might be enough.
The focus needs to be changed. There are a lot of positive things to talk about. Rather than continuing to promote the NME, which I feel any comments would do, he should be visible, and shown to be moving on with a successful tour and new music.
I don't think he should be hiding or not talking to press, if that's what he is doing.
