Mistletoe is the common name for obligate hemi-parasitic plants in several families in the order Santalales. These plants grow attached to and penetrating within the branches of a tree or shrub by a structure called the haustorium, through which they absorb nutrients from the host plant.

The name was originally applied to Viscum album (European Mistletoe, Santalaceae), the only species native in Great Britain and much of Europe. European mistletoe, Viscum album is readily recognized by its smooth-edged oval evergreen leaves borne in pairs along the woody stem, and waxy white berries in dense clusters of 2 to 6. In America the genus Viscum does not grow wild but the Eastern Mistletoe (in the genus Phoradendron) is similar, but has shorter, broader leaves and longer clusters of 10 or more berries.

Viscum album is a poisonous plant that causes acute gastrointestinal problems including stomach pain, and diarrhea along with low pulse. However, both European Mistletoe and the North American species, Phoradendron serotinum, are commercially harvested for Christmas decorations.

Sir Cliff Richard, OBE (born Harry Rodger Webb; 14 October 1940) is a British pop singer, musician, performer, actor, and philanthropist. With his backing group The Shadows, Richard, originally positioned as a rebellious rock and roll singer in the style of Little Richard and Elvis Presley, dominated the British popular music scene in the pre-Beatles period of the late 1950s and early 1960s. His 1958 hit single "Move It" is often described as Britain's first authentic rock and roll song, and John Lennon once claimed that "before Cliff and the Shadows, there had been nothing worth listening to in British music." A conversion to Christianity and subsequent softening of his music later led to a more middle of the road pop image, sometimes venturing into gospel music.

Over a 53-year career, Richard has become a fixture of the British entertainment world, amassing many gold and platinum discs and awards, including three Brit awards and two Ivor Novello awards. He has had more than 130 singles, albums and EPs make the UK Top 20, more than any other artist and holds the record (with Elvis Presley) as the only act to make the UK singles charts in all of its first six decades (1950s–2000s). He has achieved 14 UK No. 1 singles (or 18, depending on the counting methodology) and is the only singer to have had a No. 1 single in the UK in six consecutive decades: the 1950s through to the 2000s (discounting digital downloads and counting only CDs, he had a UK No. 1 single in the 2000s). Richard is the biggest selling singles artist of all time in the UK, with total sales of over 21 million and has reportedly sold an estimated 250 million records worldwide.
