More info
They broadcast two time part 4???????, but with different of length 56 and 83 minutes http://www.protonradio.com/show.php?showid=335
So we think that part 4 from 17-04-2009 is in real part 3, Muts be, becaucse that's the part that we would be missing than.
Sorry for the misunderstanding, but hat's in hands off Proton Radio, you can see for yourself, sorry for it.
