Mariah Carey (born March 27, 1970) is an American singer, songwriter, record producer, and actress. She made her recording debut in 1990 under the guidance of Columbia Records executive Tommy Mottola, and released her self-titled debut studio album, Mariah Carey. The album went multi-platinum and spawned four consecutive number one singles, on the U.S. Billboard Hot 100 chart. 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. During the recording of the album Carey began to deviate from her pop background, and slowly traversed into R&B and Hip-hop. After her separation from Mottola, this musical change was evident with the release of Butterfly (1997).

John Robert "Joe" Cocker, OBE (born 20 May 1944) is an English rock and blues singer, who came to popularity in the 1960s, and is most known for his gritty voice, his idiosyncratic arm movements while performing, and his cover versions of popular songs, particularly those of the Beatles.

He is the recipient of several awards, including a 1983 Grammy Award for his #1 hit "Up Where We Belong", a duet he performed with Jennifer Warnes. He was ranked #97 on Rolling Stone's 100 greatest singers list.

Cocker was born on 20 May 1944 at 38 Tasker Road, Crookes, Sheffield, West Riding of Yorkshire. He is the youngest son of a civil servant, Harold Cocker, and Madge Cocker. According to differing family stories, Cocker received his nickname of Joe either from playing a childhood game called "Cowboy Joe" or from a local window cleaner named Joe.

Cocker's main musical influences growing up were Ray Charles and Lonnie Donegan. Cocker's first experience singing in public was at age 12 when his elder brother Victor invited him on stage to sing during a gig of his skiffle group. In 1960, along with three friends, Cocker formed his first group, the Cavaliers. For the group's first performance at a youth club, they were required to pay the price of admission before entering. The Cavaliers eventually broke up after a year and Cocker left school to become an apprentice gasfitter while he pursued a career in music.
