Regarding Alan exact input nobody knows the thruth here.
the point is that officially all songs are written by MK, Alan Clark was never credited for anything,
so stating to have been a big part of the arragement is a very bold statement from many points of view
he even states that outside Dire Straits he is "meticulous" about being credited, but with Dire Straits zero credits ?
and why ? it's just a bunch of BS imo
Moreover I have checked with Mimmo Carrata, the biggest collector in the world as many of you know,
he knows everything and has everything (including Telegraph Road Studio without the fade out
and Tunnel of Love Studio with MK's guitar intro and so many other stuff,
I will go to his home sooner or later and then report everything here,
we have known for 30 years and don't know why I haven't gone yet (well the other side of italy is not close actually),
he has invited me many times and promised I will be stunned),
well the point is that he says Alan Clark has written nothing and arranged nothing.
