Thanks M
The example you give does not make 'and'' redundant in (2). I absolutely see that (2) could work with or without and', meaning the same thing either way.
When 'and' is used it has a use and a meaning, particularly in the surface.
'like' seems to be different in that I can see no legitimate role for it.
I have seen your suggestion for 'like', which is better than I could do. I was asking you if you find this explanation satisfying.
As presently advised, I am not convinced. So I wondered if we are all barking up the wrong tree.
