Yes, Tannen's DID publish a soft-cover KABBALA. The original edition, after being printed, was dumped because of controversial sections. It was typeset and another print run was made. The covers of each version are DIFFERENT. There may be 5 surviving copies of the original print run. The others were destroyed. The years? 1975-76. I guess this volume could be considered Vol. 3? THE LOST PAGES is a different book.
What happened between 1973 and 1980 is "a long story" that involves becoming a single parent with custody of 4 children, three mysterious women, working two jobs, and dealing with infighting amongst the ranters and roustabouts in magic-dumb.
