Well, the technical part of this, beat the everloving cr*p out of it. 
Don't forget to use a little Liquid Wrench or somesuch at the hub 
area.

Now down to the finer points.  Assuming that all bolts are removed.
Get big screwprydriver and place between drum and plate that holds 
the brake goodies.  With other hand use judiciously applied smacks 
with a hammer, moving around.  Warning, the drum may pop off and land 
in your lap.  =8-0  This didn't work on mine :-(

Next level of mayhem.  I found that by dismantling my cheapo gear 
puller I could wedge one of the ends of the puller arms between the 
drum and plate rotate it 90 degrees and tuck the other end of the arm 
in the same space.  This results in applying a LOT of force on the 
drum in three spaced locations.

About this time the kiddies were appearing to join daddy in the fun 
of beating the bus with a hammer.  Had to shoo'em away, fearing the 
drum would sail into the neighbour's yard.  I, being the type with a 
small dislike for flying brake drums, also positioned myself at all 
times away from the launch trajectory.

Anyway back to the story.  After applying LOTS of force on the 
drum/hub interface, I walked away (around the other side of the bus) 
to get a bigger hammer.  Remember if it don't fit, force it, and it 
if STILL don't fit, use a bigger hammer.

A few steps later, TWANG.  The drum separated from the hub all by 
itself! (dang, I wanted to use my bigger hammer).  Landed about 1 
foot away from the hub.

Hey, just wait a minute, I've been fibbin' all along.  Just 
remembered that I was doing this on my '64 Ford truck.  Anyway I like 
the story, it's friday, and I would do this on my bus if I had too, 
though the brake backing plates are a little less beefy.

Be creative in the ability to apply steady force on the drum. 
A hammer sets up a vibration that will eventually loosen the drum.

Don't forget to apply a little anti-sieze upon re-assembly.
