 \section{Introduction}
 
+After every practice or dance-out, the musicians of Cry Havoc Botley
+Morris like to have a little music-playing session. And, of course,
+the musicians provide the music we dance to.
+
+Havoc musicians come in all shades of experience and ability.
+This collection is intended to help those like me who are inexpert with
+instrument and folk music generally, but have a little musical background.
+
 \input{intro.txt}
 
+Being folk tunes, many of the tunes herein have many variations.
+The music presented here is my attempt at reflecting what the musicians
+of Cry Havoc play. I'm in no way suggesting that they are
+in any way \emph{correct}. This is just how we go about them.

 All tunes in this book are believed to be in the public domain, or at the
 very least enjoy widespread currency on the folk music scene. If I have
 inadvertantly transgressed on anyone's copyright, please contact me at
 \href{mailto:dottes@cryhavoc.org.uk}{\texttt{dottes@cryhavoc.org.uk}} and I will
 remove the offending tune.
