Yeh this book is on its way to me at this moment,looking at the cover of the book,there seems to be many of the usual suspects,but i like Richard Morton Jacks writing so i look forward to receiving this,i also know that RMJ has started a label called FLASHBACK,maybe after the fine magazine he was behind which has not been out for a while now,so i don't know if he has stopped doing this mag.I just received John Wonderling "Day Breaks"cd reissued on the FLASHBACK label,and its a little beauty with liners,photos and extra tracks and most importantly great sound quality of the music,i'm sure this is the second reissue by FLASHBACK,and for the life of me i can't remember what the other is.Can anyone tell me what it was??Much obliged if you could!!

Their site lists releases by Mighty Baby, Trader Horne, Mandrake Memorial, Spirit and Various-Songs The Bonzos Taught Us. interestingly no mention of John Wonderling though.
They have had an issue of their great mag out for ages. Hope they're still doing them.

This is the other Flashback label that reissues bootlegs.
