Lusitanian --Bell Beaker?

Reig Vidal over at Substrate, explained that
Lusitanian is linked archeologically to the Bell
Beaker Culture.
I'm not sure if he's on this list but I hope, so he
can elaborate.
Does anyone know that this link to be certain?
As we know, Lusitanian resembles both Celtic and
Italic but, unlike Celtic, maintained /p/. Until Reig
posted, my guess was that it came from somewhere
around the Alps, perhaps N. Italy before passing into
Spain and that it was probably the same language that
Coromines referred to as Sorotaptic and others
(including Lapesa, I think --unless he was citing
someone else) termed Ligurian or Illyrian.
Reig explained that Bell Beaker culture was from N.
Germany, Benelux, etc. and that's what I had seen but
Wikipedia has it all over W Europe.
The dates are about a 1,000 years earlier than what I
would have expected for Lusitanian. Given its
closeness to Celtic and Italic, I would have expected
that it entered shortly before Celtiberian was
established in Iberia. Maybe c. 1,000 BCE.
I'll you all answer this
