Hello Goodbye: That pic you posted of the 5 early Beatles is very interesting to me in the following aspects:
1) Note that John, George, Paul and Stu are wearing light suits and black shirts. Pete is wearing a dark suit and a light tie.
2) Note that John's, George's, and Paul's guitar necks are all pointed at Pete.
3) Note that Stu's bass guitar neck points out of the scene (away from the others).
Maybe I'm reading meanings into this but here I go:
1) Pete is not appearing as one of them by virtue of his appearance.
2) The guitars of 3 Beatles all pointing at Pete seem to signify him as a target for eventual dismissal from the band.
3) Stu's guitar signals out (not in) in the Beatles scene. His exit from the group was to be his future.
So, thanks for posting the pic!
