Another possibility (though highly unlikely) is that disc 2 is the actual beginning of the plot and that the story ends with Pink's suicide or descent into madness with "Goodbye Cruel World" on Disc 1. I'm rather disinclined to believe this one, but one can interpret that after the wall is torn down, Pink performs "In the Flesh?" which starts disc 1 and the rest of disc 1 is Pink recalling his past in flashback mode until he decides to commit suicide or descend into madness (like Syd).

The other question that comes to mind is whether Pink is more reflective of Roger Waters or Syd Barrett. I suppose Roger admits that the story is somewhat autobiographical with peices of Syd in there, but as the audience listening to the album, there are many ways to interpret who Pink really is. Any ideas on this? The Pink persona was really introduced on "Have a Cigar" from WYWH albeit in a rather sarcastic sense to point out the shallow nature of record co. execs, but if one chooses to, one can make an argument that WYWH is linked to the Wall for this reason. Since the Wall never chronicles Pink's rise to stardom, one can suggest that WYWH may function as a document of this part of the story. Although we all know that the band may not have intended this and that WYWH is really about Syd, sometimes it's fun to speculate these possibilties if just for fun.
