Yes, about Beryl Booker - I found her, too, on Wikipedia last night. And it is somehow strange/funny that her family name is BOOKER, but I think the tobacco line in the lyrics make it pretty clear that Mark means Beryl Bainbridge with this song... but maybe, who knows, both names might have resonated in Mark's mind..
(I also often like to think that he heard the name "Redbud Tree" maybe in a conversation with Bob or during an American tour leg or maybe saw one and was told these trees are called Redbud Trees, and automatically the pure sounding of the word made him think Redbud Tree, shelter me, shelter me, and off his songwriting sould went and the rest was simple... same with Dog eat Dog, rat eat rat, when it comes to EATING at McDonalds and the line in Ray Krocs book.. so this might be the initial word for it, as Booker and Booker price might be for Beryl - and he is married to a writer and loves literature.. but I am going off topic too much.. )
So, Beryl, the first Non-Smoker-Song about a writer in Mark's universe, after Harry in In The Gallery and the Artist in Let It All Go... now we have Beryl!
