Getting the section/subsection name...

[Nick DeClario]

Here's an easy one, I hope...   I am trying to get section and
subsection numbers of my document into the header.  What is the command
to use to get the current section?  I have the section number but not
the name.

I am currently using:

\fancyhead[LE]{Section - \bf \thesection}

Where 'Section' is I would like to replace with the actual section
name.  Thanks.
