One trick no-one has mentioned that worked for me a few years ago. It might help someone. It involves sacrificing the seat post.
1-- saw off top of seat post (I didn't need to because post had broken under me when out on a ride)
2-- find, beg borrow or steal an old style quill handlebar stem with handlebars attached.
3-- Insert handlebar stem down the inside of seat pillar and tighten expander bolt
4-- Twist on the handlebars; they give you a fair bit of leverage and yank seat post out
