"Xmas" is a common abbreviation of the word "Christmas". It is sometimes pronounced /ˈɛksməs/, but it, and variants such as "Xtemass", originated as handwriting abbreviations for the typical pronunciation /ˈkrɪsməs/. The "-mas" part is from the Latin-derived Old English word for "Mass", while the "X" comes from the Greek letter Chi, which is the first letter of the Greek word Χριστός, translated as "Christ".

There is a common misconception that the word Xmas is a secular attempt to remove the religious tradition from Christmas by taking the "Christ" out of "Christmas".

"Xmas" is deprecated by some modern style guides, including those at the New York Times,The Times, The Guardian, and the BBC.Millicent Fenwick, in the 1948 Vogue's Book of Etiquette states that "'Xmas' should never be used" in greeting cards.The Cambridge Guide to Australian English Usage states that the spelling should be considered informal and restricted to contexts where concision is valued, such as headlines and greeting cards.The Christian Writer's Manual of Style, while acknowledging the ancient and respectful use of "Xmas" in the past, states that the spelling should never be used in formal writing.

John Winston Ono Lennon, MBE (9 October 1940 – 8 December 1980) was an English musician and singer-songwriter who rose to worldwide fame as one of the founder members of The Beatles, one of the most commercially successful and critically acclaimed acts in the history of popular music. Together with Paul McCartney, he formed one of the most celebrated songwriting partnerships of the 20th century.

Born and raised in Liverpool, Lennon became involved as a teenager in the skiffle craze; his first band, The Quarrymen, evolved into The Beatles in 1960. As the group disintegrated towards the end of the decade, Lennon embarked on a solo career that produced the critically acclaimed albums John Lennon/Plastic Ono Band and Imagine, and iconic songs such as "Give Peace a Chance" and "Imagine". After his marriage to Yoko Ono in 1969, he changed his name to John Ono Lennon. Lennon disengaged himself from the music business in 1975 to devote time to raising his infant son Sean, but re-emerged with Ono in 1980 with the new album Double Fantasy. He was murdered three weeks after its release.

Céline Marie Claudette Dion, CC OQ, (French pronunciation: [selin djɔ̃] ( listen); born March 30, 1968), is a Canadian singer. Born to a large family from Charlemagne, Quebec, Dion emerged as a teen star in the French-speaking world after her manager and future husband René Angélil mortgaged his home to finance her first record. In 1990, she released the English-language album Unison, establishing herself as a viable pop artist in North America and other English-speaking areas of the world.

Dion had first gained international recognition in the 1980s by winning both the 1982 Yamaha World Popular Song Festival and the 1988 Eurovision Song Contest. Following a series of French albums in the early 1980s, she signed on to CBS Records Canada in 1986. During the 1990s, with the help of Angélil, she achieved worldwide fame after signing with Epic Records and releasing several English albums along with additional French albums, becoming one of the most successful artists in pop music history. However, in 1999 at the height of her success, Dion announced a hiatus from entertainment in order to start a family and spend time with her husband, who had been diagnosed with cancer. She returned to the top of pop music in 2002 and signed a three-year (later extended to almost five years) contract to perform nightly in a five-star theatrical show at the Colosseum at Caesars Palace, Paradise, Nevada.

Following her marriage to Mottola in 1993, a series of hit records, including Emotions (1991), Music Box (1993) and Merry Christmas (1994), established her position as Columbia's highest-selling act. Daydream (1995), made music history when the second single, "One Sweet Day" a duet with Boyz II Men, spent a record sixteen weeks on top of the Billboard Hot 100, and remains the longest running number one song in US chart history.
