Far from 100 % Wishbone Ash and far from being a "written" book:
This is a collection of wikipedia pages related to a year in music. These two are of years 1970 and 1972. Both mention Wishbone Ash on the cover. The "book" telling about year 1970 has a picture of Muddy Manninen on its cover [sic].
The "editor" has just copied and pasted wikipedia pages related to the year in question and that's it. In Wishbone Ash's case, it's the same wikipedia page in both books. How Creative (Common) is this...
