Glass Onion

The lyrics of The Beatles'  Glass Onion contain PID/Paul was Replaced clues and have been interpreted several ways.  Instead of seeing esoteric, opaque, and obscure meanings to the clues, if you look at them in  more literal and punning ways---like working-class people would write them--- I think you will get closer to the truth of the meanings.

Three lines are instructive to this:
1.)  The line, "We're as close as can be"  can be read, "We ARE as close as can be" OR "We  WERE as close as can be."

2.)  "Looking through the bent-backed tulips" line could easily be a pun for "bent-backed TWO LIPS":   lips being pressed onto a clear surface.

3.)  And "The walrus was Paul" line could mean "Paul" was dressed in a walrus costume for the Magical Mystery Tour album OR that Paul died.
