[e.k.]

Is it possible in MS to change a (small printed) 2-page into two separate (full size) pages and if so, how?

You can double the page  e.g. in the Song Editor (page order 1,1 instead of 1-1) and the use  page cropping on each  page.

Thanks! I'll try that. 
I tried now but the particular double pages are each named as a single number. In this case, 36,35,37. I don't see a way to separate each of the three.
Well, maybe I didn't fully understand your directions. hmm 

@Michael_G:
Thx a lot, had the same "problem", didn´t realize this easy way.
