Getting the approver name from task approvers

Hi,

 I am having a Request Approval in which there are two groups assigned there for approval. I have given All must approve and not given the check create individual tasks for all group members. It is working perfect. but now I need to fetch the approver name from the group, and need to show in the form itself. How can I get the approver name if the task is assigned to a group.

 Thanks,

Siju George.
