You may still want to try and move the car a bit while on its wheels. That may unstuck the brake shoe liners from the drums (you need to replace brake shoes anyway). If car does not drive, place large crow bar on wheel (using two wheel bolts) and try to rotate the wheel if there is space. Once wheels rotate, get drum off. I would resort to burner as a last resort.
