Question: What nickname is often applied the singer of the song If Anyone Falls ? 

Context paragraphs:
Convenanter Church: Convenanter Church is a misspelling of Covenanter Church, a nickname often applied to and used by the Reformed Presbyterian Church in the past.  In the United States, "Convenanter Church" also refers to two buildings once used by this denomination, which are listed by this misspelling on the National Register of Historic Places:

If Anyone Falls: "If Anyone Falls" is a 1983 song by the American singer/songwriter Stevie Nicks.  It was the second single from her second solo album, "The Wild Heart".  The song peaked at No. 14 on the "Billboard" Hot 100 and reached number eight spot on the "Billboard" Top Rock Tracks chart.

Big Five personality traits: The Big Five personality traits, also known as the five factor model (FFM), is a model based on common language descriptors of personality.  When factor analysis (a statistical technique) is applied to personality survey data, some words used to describe aspects of personality are often applied to the same person.  For example, someone described as "conscientious" is more likely to be described as "always prepared" rather than "messy".  This theory is based therefore on the association between words but not on neuropsychological experiments.  This theory uses descriptors of common language and therefore suggests five broad dimensions commonly used to describe the human personality and psyche.  The five factors have been defined as openness to experience, conscientiousness, extraversion, agreeableness, and neuroticism, often represented by the acronyms "OCEAN" or "CANOE".  Beneath each proposed global factor, a number of correlated and more specific primary factors are claimed.  For example, extraversion is said to include such related qualities as gregariousness, assertiveness, excitement seeking, warmth, activity, and positive emotions.

Macromolecular assembly: The term macromolecular assembly (MA) refers to massive chemical structures such as viruses and non-biologic nanoparticles, cellular organelles and membranes and ribosomes, etc. that are complex mixtures of polypeptide, polynucleotide, polysaccharide or other polymeric macromolecules.  They are generally of more than one of these types, and the mixtures are defined spatially (i.e., with regard to their chemical shape), and with regard to their underlying chemical composition and structure.  Macromolecules are found in living and nonliving things, and are composed of many hundreds or thousands of atoms held together by covalent bonds; they are often characterized by repeating units (i.e., they are polymers).  Assemblies of these can likewise be biologic or non-biologic, though the MA term is more commonly applied in biology, and the term supramolecular assembly is more often applied in non-biologic contexts (e.g., in supramolecular chemistry and nanotechnology).  MAs of macromolecules are held in their defined forms by non-covalent intermolecular interactions (rather than covalent bonds), and can be in either non-repeating structures (e.g., as in the ribosome (image) and cell membrane architectures), or in repeating linear, circular, spiral, or other patterns (e.g., as in actin filaments and the flagellar motor, image).  The process by which MAs are formed has been termed molecular self-assembly, a term especially applied in non-biologic contexts.  A wide variety of physical/biophysical, chemical/biochemical, and computational methods exist for the study of MA; given the scale (molecular dimensions) of MAs, efforts to elaborate their composition and structure and discern mechanisms underlying their functions are at the forefront of modern structure science.

List of philanthropists: A philanthropist is someone who engages in philanthropy; that is, someone who donates his or her time, money, and/or reputation to charitable causes.  The term may apply to any volunteer or to anyone who makes a donation, but the label is most often applied to those who donate large sums of money or who make a major impact through their volunteering, such as a trustee who manages a philanthropic organization.

Trifolium repens: Trifolium repens, the white clover (also known as Dutch clover, Ladino clover, or Ladino), is a herbaceous perennial plant in the bean family Fabaceae (Previously referred to as Leguminosae).  It is native to Europe and central Asia.  One of the most widely cultivated types of clover, it has been widely introduced worldwide as a forage crop, and is now also common in most grassy areas (lawns and gardens) of North America and New Zealand.  The species includes varieties often classed as small, intermediate and large, according to height, which reflects petiole length.  The term “white clover” is applied to the species in general, “Dutch clover” is often applied to intermediate varieties (but sometimes to smaller varieties), and “ladino clover” is applied to large varieties.

Snail: Snail is a common name loosely applied to shelled gastropods.  The name is most often applied to land snails, terrestrial pulmonate gastropod molluscs. However, the common name "snail" is also used for most of the members of the molluscan class Gastropoda that have a coiled shell that is large enough for the animal to retract completely into.  When the word "snail" is used in this most general sense, it includes not just land snails but also numerous species of sea snails and freshwater snails. Gastropods that naturally lack a shell, or have only an internal shell, are mostly called "slugs", and land snails that have only a very small shell (that they cannot retract into) are often called "semi-slugs".

Glaze (cooking technique): A glaze in cooking is a coating of a glossy, often sweet, sometimes savoury, substance applied to food typically by dipping, dripping, or with a brush.  Egg whites and basic icings are both used as glazes.  They often incorporate butter, sugar, milk, and certain oils. For example, doughnut glaze is made from a simple mixture of powdered or confectioner's sugar and water that the doughnuts are dipped in, or some pastry doughs have a brushed on coating of egg whites.  Glazes can also be made from fruit or fruit juice along with other ingredients and are often applied to pastries.  Recently, a type of glazed cake known as an entremet, has gained worldwide popularity after a Russian confectioner's Instagram page went viral in 2016.  In contrast to frosted cakes, these pastries use "mirror glaze," which is so glossy objects reflect on the surface.  A type of savory glaze can be made from reduced stock that is put on meat or vegetables.  Some candies or confections may be coated in edible wax glazes.  Glazed ham is a ham dish prepared using a glaze.

Mr. Fixit: Mister Fixit is a nickname often applied to a man who is skilled at repairing things.  It is also:
