I already wrote a lengthy (Andrew Fisher dubbed it an "emotional") review from the Warsaw gig. Did you have a chance to read it, perhaps? It's right here, on this page, under "the tour" banner.
Chris Rea kept on changing guitars for each song. This was especially true in the second part of the concert. The technician was coming and going in-between songs, sometimes just ducking behind Chris and handing him yet another instrument or putting it on the guitar rack. Chris started off with a Hofner guitar and at that stage Robert Ahwai played almost all solos. Chris was getting ready to "join the action", so to say, and slowly was taking over from Robert. All this took place on the instrumental ("The Delmonts") part.
While playing "Josephine", just like on the "farewell tour", Chris switched from a "Fender" to a banjo. On the FHBN part he played mostly Fenders, including the "Pinky" (Pinkie?) and "Bluey" (described in several articles as being the oldest "Fenders" in Chris' possession), which I easily recognized as they are scratched and some paint on them is either peeling off or just fading away.... These guitars, though, are well maintained (up kept)...
Chris is a left-handed fellow, all right, but he played exclusively with his right hand (picking the strings with), although whenever he gestured he used his left hand. When he introduced (sort of) his musicians by name, when they played some long solos, he also used his left hand to do that, even though he would point out to someone at his right. The base player Colin Hodgkinson, being a lefty, played all the time with his left hand.
Robert Ahwai, as I already said, played solos on the Delmonts and in the second part, on the FHBN, but not as often as in part one. He used two, perhaps three different guitars in all.
The sound difference - between a Hofner and a Fender - was there and it's very characteristic, indeed. The Hofner sounds more like "The Beatles", "the Shadows", "The Ventures" and "The Searchers", as all of these bands played on Hofners.
The guitar technician (I once remembered his name) had a battery of guitars just standing in a stand to the left side of the stage near the curtain (lined up just like bicycles!) and he would mend them there sitting on the chair, being all the time at the ready.
He moved, as I noted, very gently in the shadow between Chris and Robert Ahwai. The base player - Colin Hodgkinson - played through the concert on his only guitar left hand tuned, most of the time bent over the instrument and rarely raising his head up. The drummer - Martin Ditcham - had the hardest job because the band played without any break (not counting even the breaks in-between some song, because some numbers just went from one note overlapping onto another.)
The atmosphere was (somehow) tense at the start of the concert, I would say, as people anticipated and awaited what's going to happen next. Furtermore, "The Delmonts" part was deliberately shortened to only six (6) songs played - in fact - en bloc. It all happened very fast.
And one more observation. After the gig, with only one encore, the stage hands moved in quickly to dismantle everything even though we hadn't left the hall....
You might get some answers to your questions in the "documentary" part of the two DVD recordings of "The Road to Hell & Back." If you don't have it yet, buy it, please.
I don't know if it's available over the big pond, though.
