They'd None of 'em Be Missed

As most Victorianists and/or Gilbert & Sullivan fans are aware, since very early on in The Mikado's career, the Lord High Executioner's "As Someday It May Happen" (the "little list" song) has not been performed as originally written.  Richard Suart and A. H. Smyth have now edited an entire anthology devoted to the song's many mutations.   On YT, courtesy of the English National Opera, Suart demonstrates some alternate versions  (1 2) and offers some hints about how to revise the song (3); you can also see a D'Oyly Carte version (1992).  (Via Talkin' Broadway.)
