Question: Horse's Neck and John Collins, are which type of item?

Context paragraphs:
Baroque horse: The term baroque horse describes a group of horse breeds, usually descended from and retaining the distinctive characteristics of a particular type of horse that rose to prominence in Europe during the Baroque era, after significant development throughout the Middle Ages.  It describes the type of agile but strong-bodied descendants of horses in the Middle Ages such as the destrier.  Specific ancestors of this type include the Neapolitan horse, and the Iberian horse of Barb ancestry known in the Middle Ages as the Spanish Jennet.  They are characterized by powerful hindquarters, a muscular, arched neck, a straight or slightly convex profile, and usually a full, thick mane and tail.  These horses are particularly well suited for the "haute ecole" discipline of classical dressage.

Horse's Neck: A Horse's Neck is an American cocktail recognised by the IBA, identifiably sporting a long, curling strip of lemon rind.

Edward Gilbert Abbott: Edward Gilbert Abbott (1825–1855) was the patient upon whom William T. G. Morton first publicly demonstrated the use of ether as a surgical anesthetic.  The operation was done in an amphitheater at the Massachusetts General Hospital now known as the Ether Dome on 16 October 1846.  After Morton administered the ether, surgeon John Collins Warren removed a portion of a tumor from Abbott's neck.  After Warren had finished, and Abbott regained consciousness, Warren asked the patient how he felt.  Reportedly, Abbott said, "Feels as if my neck's been scratched."  Warren then turned to his medical audience and uttered "Gentlemen, this is no Humbug."  This was presumably a reference to the unsuccessful demonstration of nitrous oxide anesthesia by Horace Wells in the same theater the previous year, which was ended by cries of "Humbug!"  after the patient groaned with pain.

Collins–Valentine line: The Collins–Valentine line, or Valentine–Collins line, is the boundary at approximately 45 degrees north latitude that separates the province of Quebec from the states of New York and Vermont.

Thomas Collins (Australian politician): Thomas Joseph "Tom" Collins (6 April 1884 – 15 April 1945) was an Australian politician and stock and station agent, born at Yass, New South Wales to storekeeper John Collins and Mary, née Hartigan.  In 1902, having attended the local Catholic school, he enlisted in the 5th Battalion, Australian Commonwealth Horse, to fight in the Boer War.  However, by the time Collins's unit arrived, the war had finished.

Ether Dome: The Ether Dome is a surgical operating amphitheater in the Bulfinch Building at Massachusetts General Hospital in Boston.  It served as the hospital's operating room from its opening in 1821 until 1867.  It was the site of the first public demonstration of the use of inhaled ether as a surgical anesthetic on October 16, 1846, otherwise known as Ether Day.  Crawford Long, a surgeon in Georgia, had previously administered sulfuric ether in 1842, but this went unpublished until 1849.  The Ether Dome event occurred when William Thomas Green Morton, a local dentist, used ether to anesthetize Edward Gilbert Abbott.  John Collins Warren, the first dean of Harvard Medical School, then painlessly removed part of a tumor from Abbott's neck.  After Warren had finished, and Abbott regained consciousness, Warren asked the patient how he felt.  Reportedly, Abbott said, "Feels as if my neck's been scratched".  Warren then turned to his medical audience and uttered "Gentlemen, this is no Humbug".  This was presumably a reference to the unsuccessful demonstration of nitrous oxide anesthesia by Horace Wells in the same theater the previous year, which was ended by cries of "Humbug!"  after the patient groaned with pain.

The Defiants: The Defiants were a Minnesota based garage rock band in the 1960s.  The Defiants were formed in Clara City, Minnesota by Steve Henslin, Doug Gerken, Donny "Mixer" Mickels and Dewayne "Smitty" Smith.  Steve Henslin later left and Mike Shaw (bass and vocals) took over leadership of the band.  Mike brought in his brother Terry R. Shaw on drums and vocals.  The band consisted of the Shaw brothers, Loren "Wally" Walsted on lead guitar (who died from a heart attack on Sept. 3.  2014), and John Collins on rhythm guitar.  This form of the group stayed together from 1963 to 1967 and recorded one single; a cover of Bob Dylan's "Maggie's Farm" backed with a cover of "Bye Bye Johnny."  The Defiants broke up in 1967 when John Collins was drafted for service in the Vietnam War but opted to join the Marines instead.  Mike Shaw and Terry R. Shaw later formed the group Shaw-Allen-Shaw with Jim Allen.  That group recorded two albums, set many ballroom attendance records and, in 2006, was inducted into the Mid-America Music Hall of Fame (formerly the Minnesota Rock/Country Hall of Fame).  Terry R. Shaw is the author of two books about growing up in the '50 in a small town (Litchfield, Minnesota).  The books are called "Terry Tales" and "Terry Tales 2".  In addition he has written three books about Buddy Holly, the Beatles and Elvis Presley, which can be viewed online for free.  Shaw has also written several songs, the videos of which can be seen on www.youtube.com.
