I was just popping around amazon.co.uk & looking for the Uk book on 
tape versions - there's 2 different versions of Book1 - the "regular" 
and the "adult" edition - I know there's no difference between the 
books other than the covers - is there any difference between the 
regular & adult tapes? The adult ones are at 
http://www.amazon.co.uk/exec/obidos/ASIN/1855494981/qid=967568034/sr=1
-11/026-6370701-7469230
and yes, they too are read by Stephen Fry.

Also, have book on tape versions of Azkaban & GoF been released yet? 
I love jim dale, but do like stephen fry a lot & would like to give 
one of the UK tapes a try.
