[texhax] memoir package, \begin{verse}[\versewidth], poem title

[Mica Semrick]

I am using the memoir package to try and typeset some poems, and I am  
running into a slight problem. I am using the verse environment with  
the \versewidth command to center the poem. I would like to have the  
title of the poem flush with the body of the poem. How would I do this?

This is where I am currently stuck in the code:

\documentclass[12pt,oneside]{memoir}

\pagestyle{plain}
\chapterstyle{dash}
\renewcommand{\PoemTitlefont}{%
\normalfont\sffamily\hspace{\vleftmargin}} %Remove centering from the  
poem title

\begin{document}

\settowidth{\versewidth}{this is a pretty long line in my poem}
\PlainPoemTitle
\PoemTitle{My Great Poem Title}
\begin{verse}[\versewidth]

this is the body of my poem\\
and its pretty bad\\
please help me with my problem\\
and i will be quite glad\\
and: his is a pretty long line in my poem\\
\end{verse}
\newpage

\end{document}

Any help would be greatly appreciated, I've been working on this for a  
few days with no results.

Best,
Mica
