After searching through a few hundred flickr images tagged "piccadilly circus", this is the closest I have found in terms of persepective (and hence shooting location):

It's not identical - the shooter in the magazine shot was standing a bit to the left and a bit further away from the statue, and with a lower camera position.
It would take about a 75% crop of the flickr image to get approximately the same field of view as the magazine image. The lickr image was taken with an 18mm lens on en EOS550D, which has a 1.6x crop factor, so equivalent to about 28.8mm on a 35mm camera. Although it has been edited in photoshot, the image size is the same as the native sensor size, so it is unlikely that it has been cropped. Allowing for the 75mm crop required to equalise the field of field gives 38mm on a 35mm camera.
However compare the size of the statue compared to the building on both shots. On the magazine shot the statue appears smaller compared to the building, so the camera must have been further away from the statue, and using a longer lens.
Based on this my guess would be about a normal lens, either the 90mm or the 110mm on the RZ-67.
