Long shot I know- Brennan manning has a book The Ragamuffin Gospel that is on audio cd?

I have seen abridged and unabridged ones for sale on the internet- The unabridged is 6 hrs 42 minutes but I have seen more than one saying it is the “abridged” version also at 6hr 42 minutes…does anyone have a copy of either and especially how long is the abridged version…thanks
I am not concerned with the actual paperback book -I have that ..I am interested in the AUDIO CD version of the book- the abridged/unabridged differences-thanks
