In his own words, that song was his „..first real major piece of work. Up till then it had all been sort of glib and throwaway ...“ (John Lennon in „All We Are Saying“ by David Sheff). Aha.
Frustrates me. If I could only make up throwaway glib 10% as good as he could.
First tried to tab it strictly after the songbook. A desaster. Now it is ok.
