And though not related to footnotes, you should avoid \concatenating 
strings because it will result in single line of text.  Granted, if your 
font size is small compared to the paper size, it is possible all that 
text could fit within the page margins.  In general, though, you should 
consider using \wordwrap or \wordwrap-string:

%%%%
\markup \override #'(line-width . 40)
\left-column {
  \bold \typewriter "\\wordwrap"
  \wordwrap {
  * This song has been translated by the leading Irish,
    Scotch Gaelic, Manx, Welsh, Breton, and Cornish poets
    into their native languages for singing in each Celtic
    country and at Pan-Celtic Festivals.
  }
  \vspace #1 \draw-hline
  \bold \typewriter "\\wordwrap-string"
  \wordwrap-string
  #"* This song has been translated by the leading Irish,
      Scotch Gaelic, Manx, Welsh, Breton, and Cornish poets
      into their native languages for singing in each Celtic
      country and at Pan-Celtic Festivals."
}
%%%%
