I am familiar with the writing style of Geoff Wallis and the piece certainly does bear a remarkable resemblance to the sort of prose he is likely to produce.
As he is a member of, and frequent contributor to, this forum, I think he should come out and clarify whether identical reviews in two publications under two different names are indeed his, or not.
I think he should do so at fRoots as well, but would at present be unable to do so as the thread there has been closed. I would, therefore, expect Ian Anderson to ask (indeed insist) that Mr Wallis clarifies his position all round.
I don't know whether the good Cap'n was genuinely unaware of this possibe dual identity, or whether he saw it as an opportunity to take a potshot at his longtime sparring partner, Sugar Ray Wallis.
Nevertheless, considerable grounds for doubt prevail.
