This answer works when the title is printed in the node template.
However, the base node template contains this code:
<?php if (!$page): ?>
<h2<?php print $title_attributes; ?>><a href="<?php print $node_url; ?>"><?php print $title; ?></a></h2>
<?php endif; ?>
So how do I print a field before the title when the title was already printed in the page template?
