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.

Lita Rossanna Ford (born 19 September 1958) is a British-born, American rock musician and singer who was the lead guitarist for The Runaways and achieved popularity for her solo career between the 1980s and early 2010s.

Lita Ford was born Lita Rossana Ford to a British father and an Italian mother in London, England. She moved with her family to the United States at the age of 4 and began playing the guitar at the age of 11. Her vocal range is mezzo-soprano.

In 1975 at the age of 16 she joined the all-female rock band The Runaways, for whom she played lead guitar. They then scored a record deal and released their first album in 1976.

It was not long before the all-girl formation caught the eye of the media. Lita Ford's guitar skills made her a driving force in the band and a permanent member from her arrival to the band's eventual break-up.

In 1979, disagreements were erupting within the band, who had since parted ways with producer Kim Fowley, lead singer Cherie Currie and bassist Jackie Fox. Rhythm guitarist Joan Jett wanted the band to shift more towards Ramones-influenced punk music while Ford and drummer Sandy West wanted to continue playing hard rock-oriented songs. With neither side being able to compromise, the band finally broke up that year.
