"Back on Earth" was the main single from the 1997 album The Ozzman Cometh, reaching #3 in Billboard's Mainstream Rock Tracks. It was sung by heavy metal artist Ozzy Osbourne and written by Taylor Rhodes and Richard Supa.

John Michael "Ozzy" Osbourne (born 3 December 1948) is an English heavy metal vocalist and songwriter, whose musical career has spanned over 40 years. Osbourne rose to prominence as lead singer of the pioneering English band Black Sabbath, whose dark and hard sound helped spawn the heavy metal genre. Due to Sabbath's dark style, Osbourne became known as the "Prince of Darkness". Osbourne is also known as the "Godfather of Heavy Metal".

In the early 2000s, Osbourne's career expanded when he became a star in his own reality show The Osbournes, alongside wife/manager Sharon and two of their three children, Kelly and Jack. A documentary about his life and career, God Bless Ozzy Osbourne, premiered in April 2011 at the Tribeca Film Festival and was released on DVD in November 2011. Osbourne has achieved multi-platinum status as a solo artist and with Black Sabbath and has sold over 100 million albums worldwide.

John Michael "Ozzy" Osbourne was born in Aston, Birmingham, England, on 3 December 1948. His father Jack worked shifts as a toolmaker at GEC. His mother Lillian worked for the car components firm Lucas. John was the fourth of six children. Ozzy had two brothers (Paul and Tony) and three sisters (Jean, Iris and Gillian); they lived in a small two bedroom home at 14 Lodge Road in Aston. The nickname "Ozzy" was first used when he was in primary school. Although called "John" by his first wife Thelma, Osbourne states that it has been a long time since he's recognised himself when called by his formal name.

Chris Austin Hadfield, O.Ont, MSC, CD (born 29 August 1959) is a Canadian astronaut from the Canadian Space Agency (CSA) who was the first Canadian to walk in space. Hadfield has flown two space shuttle missions, STS-74 in 1995 and STS-100 in 2001. He has served as CAPCOM for both Space Shuttle and International Space Station (ISS) expeditions. He is currently training for a long duration stay on board the ISS, which will include command of Expedition 35 in 2012–13. He will be the first Canadian to command the ISS. He is enthusiastic about the prospects for a manned mission to Mars, and when asked if he would consider a one-way journey to Mars to be the first to visit, he said "I would be honoured to be given the opportunity."

Chris Hadfield was born in Sarnia, Ontario. His parents are Roger and Eleanor Hadfield who currently reside in Milton, Ontario. Hadfield was raised on a corn farm in southern Ontario and became interested in flying at a young age—from his own words in the interview to STRF.RU, he came to the idea of being astronaut when he was nine on the day of Apollo moon landing, which he had seen on TV then. Hadfield is married to his high-school girlfriend Helene Hadfield, and they have three adult children together.

Kristian Matsson (born April 30, 1983) is a singer-songwriter from Dalarna, Sweden. Since 2006, he has released three full-length albums and two EPs. He performs under the moniker The Tallest Man on Earth. He is known for recording and producing his own records in whichever home he is currently living and states that the connection between his voice and guitar is so strong, he rarely records them as separately tracked performances. He is also known both by critics and his fans for his charismatic stage presence. Matsson is married to fellow Swedish singer-songwriter Amanda Bergman, who performs under the moniker Idiot Wind. The couple have toured extensively together, often performing songs together on stage. He has toured with Bon Iver. Matsson also fronted the band Montezumas.

Critics have compared The Tallest Man on Earth to Bob Dylan both in terms of songwriting ability and vocal style. When asked about his lyrical style, The Tallest Man on Earth explains that he began listening to Bob Dylan at fifteen, and upon hearing Dylan's cover material, he "tried to figure out where those songs came from" and became slowly exposed to early American folk, such as Pete Seeger and Woody Guthrie. But he is careful to qualify this, say "I don't consider my work to be a part of any tradition. This is how I play. This is how I write songs"

Neko Case ( /ˈniːkoʊ ˈkeɪs/; born September 8, 1970) is an American singer-songwriter, best known for her solo career and her contributions as a member of the Canadian indie rock group The New Pornographers.

Case recorded and toured for several years as Neko Case & Her Boyfriends before performing solely under her name. She primarily performs her own material, but also performs and has recorded cover versions of songs by artists such as Harry Nilsson, Loretta Lynn, Tom Waits, Nick Lowe, Buffy Sainte-Marie, Scott Walker, Randy Newman, Queen, Bob Dylan, Neil Young, Sparks and Hank Williams.

Case was born in Alexandria, Virginia, to teenage parents of Ukrainian ancestry. The original family name, changed before she was born, was Shevchenko. Her family traveled around while she was young before settling in Tacoma, Washington, the city she considers her hometown. She left home when she was fifteen. Her father was in the United States Air Force.

In 1994, Case moved to Vancouver, British Columbia, to attend the Emily Carr Institute of Art and Design. While attending school she played drums in several local bands, including the Del Logs, the Propanes, the Weasels, Cub (which featured I Am Spoonbender's Robynn Iwata), and Maow. All of these bands were local punk groups except for Cub and The Weasels, which Case described as a "country music supergroup".^{[citation needed]}
