Many of the examples in this book revolve around titles of songs, especially
\idx{Beatles} songs.  Since titles aren't covered by copyright, we didn't
need official permission for this, but nevertheless we want to acknowledge
the debt we owe to the great musicians who've added so much pleasure to our
lives.  The use of their names here does not mean that they've endorsed our
work; rather, we mean to show our respect for them.
