Vol. 4 was released after Queen's 1976 Japan tour and is a little less exciting compared to some of the other issues. It contains a Japanese translation of a letter from Brian May that was originally printed in the English-language Fan Club magazine and several pages of pictures from their recent shows. There's also a feature on the American glam band Angel, as well as several letters about them—it seems Warner Pioneer was attempting to replicate Queen's success. The articles that appear regarding Queen are all kind of uninteresting—mostly random opinions and an article on the symbolism of the different queens that appear in a typical deck of cards.
One part that IS interesting is a blurb about the Japan-only single release of See What A Fool I've Been. The blurb notes it was planned to be released on September 10th, 1976, but ultimately that didn't come to pass. Read more here.
