how do I add the author of the node commented on in the comment display.

Hi,

when I view the comments on a node I would like to display the author of the node on each comment.

I looked at node tpl and it only says print $submitted which is the same in comment.tpl so will display the submitter of the comment, not the node.

what do i need to add to display the node author next to each comment?

Thanks for any help.
