Here is the
omitted anti-scottish verse:
God grant that Marshall Wade,
May by thy mighty aid,
victory bring,
May he sedition hush,
and like a torrent rush,
Rebellious Scots to crush
God save the King.
Some notes edited from http://www.physics.usyd.edu.au/~saxton/oz/gstq.html
This verse dates from the Jacobite Rebellion of 1746, when Scottish Rebels and the French attempted to invade England with the purpose of enthroning The New Pretender, "Bonnie Prince Charlie". This verse is virtually unknown today.
I can't find any relevant reference to
Marshall Wade other than this song... if you find anything, node it!
