Question: Do both Königskinder and The Knot Garden exist in multiple versions?

Context paragraphs:
The Knot Garden: The Knot Garden is the third opera by composer Michael Tippett for which he wrote the original English libretto.  The work had its first performance at the Royal Opera House, Covent Garden, on 2 December 1970 conducted by Sir Colin Davis and produced by Sir Peter Hall.  There is a recording with the original cast.

Knot garden: A knot garden is a garden of very formal design in a square frame, consisting of a variety of aromatic plants and culinary herbs including germander, marjoram, thyme, southernwood, lemon balm, hyssop, costmary, acanthus, mallow, chamomile, rosemary, Calendulas, Violas and Santolina.  Most knot gardens now have edges made from box ("Buxus sempervirens"), whose leaves have a sweet smell when bruised.  The paths in between are usually laid with fine gravel.  However, the original designs of knot gardens did not have the low box hedges, and knot gardens with such hedges might more accurately be called parterres.

Shuo Yuan: The Shuo Yuan (), variously translated as "Garden of Stories", "Garden of Persuasions", "Garden of Talks", etc., is a collection of stories and anecdotes from the pre-Qin period (先秦) to the Western Han Dynasty.  The stories were compiled and annotated by the Confucian scholar Liu Xiang.  In many cases multiple versions of the same story are included, making the book a valuable source for the study of early texts.

Thomas Carey (baritone): Thomas Carey (29 December 1931 – 23 January 2002) was an American operatic baritone.  Born in Bennettsville, South Carolina, he served in the United States military during the Korean War.  After leaving the service he studied singing at the Henry Street Settlement and at City College of New York.  In 1970 he performed the role of Mel in the world premiere of Michael Tippett's "The Knot Garden" at the Royal Opera House in London.  From 1969 until his death of pancreatic cancer in Norman, Oklahoma he taught on the voice faculty of the University of Oklahoma.  He was married for many years to the contralto Carol Brice who had pre-deceased him in 1985.

List of decorative knots: A decorative or ornamental knot (also fancy knot) is an often complex knot exhibiting repeating patterns.  A decorative knot is generally a knot that not only has practical use but is also known for its aesthetic qualities.  Often originating from maritime use, "decorative knots are not only serviceable and functional but also enhance the ship-shape appearance of any vessel."  Decorative knots may be used alone or in combination, and may consist of single or multiple strands.

Cowboy bowline: The cowboy bowline (also left-hand bowline, Dutch marine bowline or winter bowline) is a variation of the bowline loop knot.  Some hearsay suggest the Dutch Navy uses (or used) this variant of the bowline because they consider it superior since the working end is not so easily pushed back by accident.  However, there is no documentation to confirm this claim, and some Dutch knot tyers outright deny it.  Another piece of unverified lore is that it is called a winter bowline because the exposed working end on the outside would blow in the wind and prevent it from freezing to the loop on ships in the north Atlantic during winter.  (This suggests that the standard bowline would be the summer bowline.) " The Ashley Book of Knots" states that it is "distinctly inferior" to the standard bowline because of its similarity to the left-hand sheet bend.  Various tests of the different versions' strengths show little difference; conjecture about either knot's vulnerability to some failure remain pretty much only that – conjectures.

James Gilchrist (tenor): James Gilchrist is a British tenor specialising in recital and oratorio singing.  He began his working life as a doctor, turning to a full-time music career in 1996.  In concert he has performed among others, Benjamin Britten's "Serenade for Tenor, Horn and Strings" with the Manchester Camerata and the Northern Sinfonia, Elgar's "The Dream of Gerontius" with the Scottish Chamber Orchestra, Tippett's "The Knot Garden" with the BBC Symphony Orchestra and Sir Andrew Davis, Bach's Christmas Oratorio with the Zurich Tonhalle Orchestra under Ton Koopman, the St Matthew Passion at the Concertgebouw, "Pulcinella" with the Ensemble orchestral de Paris, and "Die Jahreszeiten" with the Saint Louis Symphony Orchestra and with the Handel and Haydn Society at the BBC Proms.

Nail knot: The nail knot, also known as the tube knot or gryp knot, is mostly used in carp and fly-fishing.  The nail knot was named because a nail was inserted as a guide when threading the line.  Today, it is easier to use a small straw.  The nail knot is an important fishing knot used to join two lines of different diameters and allows for line diameters to diminish down to the fly.  I.E., it is useful for attaching your backing to the fly line, and your fly line to the leader, or tippet.  The knot can be tied in multiple ways and is uniform.

Königskinder: Königskinder (German for "The King's Children") is a stage work by Engelbert Humperdinck that exists in two versions: as a melodrama and as an opera or more precisely a "Märchenoper".  The libretto was written by Ernst Rosmer (pen name of Else Bernstein-Porges), adapted from her play of the same name.

Trucker's hitch: The trucker's hitch is a compound knot commonly used for securing loads on trucks or trailers.  This general arrangement, using loops and turns in the rope itself to form a crude block and tackle, has long been used to tension lines and is known by multiple names.  Knot author Geoffrey Budworth claims the knot can be traced back to the days when carters and hawkers used horse-drawn conveyances to move their wares from place to place.
