Sorry about that, Mike! Is the seat post aluminum or steel? Have you tried running a drill bit or hacksaw blade parallel to its axis, to cut a groove down the post? Your bike's previous owner is what we used to call a ZMA (Zero Mechanical Aptitude) at Bikecology/Supergo. If you ever do get that post out of there, be sure to check the seat tube and seat stay cluster for cracks.
