But why did Paul phone Holly and then she broke up? Do you think Paul advised Holly to break up because she affected Mark in a negative way on his tours? He couldn't concentrate and had to have help from a psychiatrist?
not at all.
here is an attempt to resume what is written in the book, it's about only one page that's all. Sorry for my bad translation (I have the french version of the book) :
Mark was really depressed, saw a doctor in Philadelphia and told him he was missing his girlfriend.
then the book explains who she was : singer, same manager, etc...
Paul says he phoned Holly to say to her that Mark was really depressed and that it would be nice if she could have gone to the states during DS'tour, but then she said to Paul that she had already decide to break up with Mark, and that she was going to tell it to him.
Then she phoned Mark, and Ed says that he guessed that she dumped him on phone, but of course, he didn't knew that before the gig. But when he heard Mark singing the song, he understood that something was wrong...
and he says that he sung this song like never before, and that it brought him (Ed) to tears
After that the ambience was really really bad, and that the band was really close to split. Mark didn't say any word, and spent many time beside the bus driver, without saying anything.
An then in november they went to Scandinavian countries
