         http://www.acronet.net/~robokopp/english.html)
         Some talk of Alexander, and some of Hercules / The
         British Grenadiers ca. 18th Century The British
         Grenadiers
         Some talk of Alexander,
         And some of Hercules
         Of Hector and Lysander,
         And such great names as these.
         But of all the world's great heroes,
         There's none that can compare
         With a tow, row, row, row, row, row,
         To the British Grenadier.
         2. Those heroes of antiquity
         Ne'er saw a cannon ball
         Or knew the force of powder
         To slay their foes withall.
         But our brave boys do know it,
         And banish all their fears,
         Sing tow, row, row, row, row, row,
         For the British Grenadier.
         3. Whene'er we are commanded
         To storm the palisades
         Our leaders march with fusees,
         And we with hand grenades.
         We throw them from the glacis,
         About the enemies' ears.
         Sing tow, row, row, row, row, row,
         The British Grenadiers.
         4. And when the siege is over,
         We to the town repair
         The townsmen cry, "Hurra, boys,
         Here comes a Grenadier!"
         Here come the Grenadiers, my boys,
         Who know no doubts or fears!
         Then sing tow, row, row, row, row, row,
         The British Grenadiers.
         5. Then let us fill a bumper,
         And drink a health to those
         Who carry caps and pouches,
         And wear the louped clothes.
         May they and their commanders
         Live happy all their years
         With a tow, row, row, row, row, row,
         For the British Grenadiers.
