If you run the whole script with the first line (the one not commented), 
you get output similar to this, which is correct:

 >>>
["AMN RIPQ LP WOQ SNIS. BW VIDQ, LQ'P WOQ NHNW RIPQ.", 'ULJJLIY TIZJXWNE']
 >>>

But if you use the line with the upper() call, you get this:

 >>>
["Bhe past is not dead. Dn fact, it's not even past.", 'Killiam Qaulkner']
 >>>

Now, I know the actual upper() function works, but I can't understand if 
there's a problem with *when* it's being called, or what's being done 
with it to get the second result above.
