What Is Life: "What Is Life" is a song by the English musician George Harrison, released on his 1970 triple album "All Things Must Pass".  In many countries, it was issued as the second single from the album, in February 1971, becoming a top-ten hit in the United States, Canada and elsewhere, and topping singles charts in Australia and Switzerland.  In the United Kingdom, "What Is Life" appeared as the B-side to "My Sweet Lord", which was the best-selling single there of 1971.  Harrison's backing musicians on the song include Eric Clapton and the entire Delaney & Bonnie Friends band, with whom he had toured during the final months of the Beatles.  Harrison co-produced the recording with Phil Spector, whose Wall of Sound production also employed a prominent string arrangement by John Barham and multiple acoustic rhythm guitars, played by Harrison's fellow Apple Records signings Badfinger.

Hand in Glove: "Hand in Glove" is a song by the British alternative rock band The Smiths, written by singer Morrissey and guitarist Johnny Marr.  It was released as the band's first single in May 1983 on independent record label Rough Trade Records.  "Hand in Glove" peaked at number three on the UK Indie Chart.  It did not chart (top 75) but made number 124 outside the UK singles chart.  A remixed version of the song was featured on the band's debut album, "The Smiths", in 1984.  That same year, a cover version recorded by singer Sandie Shaw featuring Smiths members Marr, Andy Rourke and Mike Joyce as backing musicians reached number 27 on the UK Singles Chart.

Rainbow (rock band): Rainbow (also known as Ritchie Blackmore's Rainbow or Blackmore's Rainbow) are a British rock band led by guitarist Ritchie Blackmore, active from 1975 to 1984, from 1993 to 1997, and from 2015 to the present.  They were originally established with Ronnie James Dio's American rock band Elf, but after their first album, Blackmore fired the backing members and continued with Dio until 1979.  Three British musicians joined in 1979, singer Graham Bonnet, keyboardist Don Airey, former Deep Purple bassist Roger Glover, and this line-up gave the band their commercial breakthrough with the single "Since You Been Gone".  Over the years Rainbow went through many line-up changes with no two studio albums featuring the same line-up.  Other lead singers Joe Lynn Turner and Doogie White would follow, and the project consisted of numerous backing musicians.  A pioneer to power metal, the band's early work primarily featured mystical lyrics with a neoclassical metal style, but went in a more streamlined, commercial direction following Dio's departure from the group.

Stone Poneys: The Stone Poneys were a folk-rock trio formed in Los Angeles, consisting of Linda Ronstadt on vocals, Bobby Kimmel on rhythm guitar and vocals, and Kenny Edwards on lead guitar.

Even at this early stage, Ronstadt was already showcasing her performances of an eclectic mix of songs, often from under-appreciated songwriters, requiring a wide array of backing musicians.

Captain Hollywood Project: Captain Hollywood Project is a famous ‘90s Eurodance music project and live touring act best known for the ground breaking crossover world hits “More and More," "Only with You" and "Flying High."  At the peak of its success in the '90s, the project itself achieved 10 Top-20 hits on European music charts.  The project was first formed in 1990 in Nuremberg, Germany by rapper/singer, dancer and music producer Tony Dawson-Harrison (aka Captain Hollywood).  When first naming the project, Harrison chose the name "Captain Hollywood Project" in order to distinguish his new music for the project from his previous music.  He also chose the name to give himself the creative freedom as executive producer to involve any singer, songwriter or producer of his choice when producing each of the new songs for the project.  Even though the act has been widely viewed as a one-man act starring Harrison as the rapper/frontman; a talented ensemble of female backup singers, dancers and backing musicians have traditionally been included in the act by Harrison.  Today, the Captain Hollywood Project is recognized as a live performing duo act starring Harrison and singer/dancer Shirin von Gehlen (aka Shirin Amour) as the project's new lead singer.  Together with their band of live musicians and dancers, Harrison and von Gehlen perform the Captain Hollywood Project hits year-round at concert venues in the United States, Canada, South America, Europe, Russia and Australia.
