Justin David Hawkins (born 17 March 1975) is an English musician and singer-songwriter, best known for being the lead singer and lead guitarist of The Darkness, alongside his brother, guitarist Dan Hawkins.
 Heavily influenced by classic hard rock and heavy metal bands of the 1970s and 1980s (particularly Queen, Aerosmith, Def Leppard and AC/DC), Hawkins is noted for his falsetto singing voice and on-stage persona.
 He was also the lead singer and guitarist for the band Hot Leg, formed in 2008, and now on hiatus.
 Since 2005 he is also active in his synthpop alter ego British Whale.
Brian Francis Johnson (born 5 October 1947) is an English singer and songwriter.
 In 1980, he became the third lead singer of the Australian rock band AC/DC, after the death of their second lead singer Bon Scott.
 He and the rest of the band were inducted into the Rock and Roll Hall of Fame in 2003.
 In March 2016, Johnson stepped down from touring on the Rock or Bust World Tour due to hearing problems.
 On 20 May 2016, Johnson stated in an interview "I've had a pretty good run" in AC/DC and implied that he might not be returning by saying "I'm just thankful, really, that I came out of it in one piece."
AC/DC are a hard rock band formed in Sydney, Australia in 1973 by brothers Angus and Malcolm Young.
 Although the band are considered pioneers of heavy metal, its members have always classified their music as "rock 'n' roll".
 AC/DC underwent several line-up changes before releasing their first album, "High Voltage", in 1975.
 Membership remained stable until bassist Cliff Williams replaced Mark Evans in 1977.
 In 1979, the band recorded their highly successful album "Highway to Hell".
 Lead singer and co-songwriter Bon Scott died on 19 February 1980, after a night of heavy alcohol consumption.
 The group briefly considered disbanding, but soon ex-Geordie singer Brian Johnson was selected as Scott's replacement.
 Later that year, the band released their best-selling album, "Back in Black".
 The band's next album, "For Those About to Rock We Salute You", was also highly successful and was their first album to reach number one in the United States.
 AC/DC declined in popularity soon after the departure of drummer Phil Rudd in 1983.
 Poor record sales continued until the release of "The Razors Edge" in 1990.
 Phil Rudd returned in 1994 and contributed to the band's 1995 album "Ballbreaker". "
Stiff Upper Lip" was released in 2000 and was well received by critics.
 The band's new album "Black Ice" was announced in June 2008 and was released on October 20, 2008.
 The album's first single, "Rock 'N Roll Train", earned AC/DC a Grammy nomination for Best Rock Group or Duo with Vocals.
 Another "Black Ice" track, "War Machine," gained AC/DC their first Grammy Award win, for Best Hard Rock Performance.
Fly on the Wall is an album by Australian hard rock band AC/DC.
 It was the band's ninth internationally released studio album and the tenth to be released in Australia.
 All songs were written by Angus Young (guitar), Malcolm Young (guitar), and Brian Johnson (vocals).
 The album was re-released in 2003 as part of the "AC/DC Remasters" series.
Long Way to the Top is the third release by North Carolina music group, Nantucket.
 The album is a tribute to AC/DC lead singer Bon Scott, who died in 1980 and features a version of their 1975 classic "It's a Long Way to the Top (If You Wanna Rock 'N' Roll)".
 This move landed Nantucket a spot with AC/DC on their "Back in Black" tour for the entire summer.
 Other popular songs on the album include "Time Bomb", "Rugburn" and "Turn The Radio On".
 "Long Way to the Top" was released on compact disc by re-issue label Wounded Bird Records in 2004.
Rockaholic is the eighth studio album by American rock band Warrant, released on May 17, 2011.
 The album features the band's third lead singer, Robert Mason, who replaced original lead singer Jani Lane in 2008.
 Lane returned to the band for a 2008 reunion tour but by the end of the year, he and the band parted ways for the second time.
 Lane had previously replaced former lead singer Jaime St. James, who performed lead vocals on the band's last album, "Born Again", and who initially replaced Lane in 2004.
"Back in Black" is a song by AC/DC, appearing as the first track on side two of their 1980 album of the same name.
 Known for its opening guitar riff, the song was AC/DC's tribute to their former singer Bon Scott.
 His replacement Brian Johnson recalled to "Mojo" magazine in 2009 that when the band asked him to write a lyric for this song, "they said, 'it can't be morbid – it has to be for Bon and it has to be a celebration.'"
 He added: "I thought, 'Well no pressure there, then' (laughs).
 I just wrote what came into my head, which at the time seemed like mumbo, jumbo.
 'Nine lives.
 Cats eyes.
 Abusing every one of them and running wild.'
 The boys got it though.
 They saw Bon's life in that lyric."
 It peaked in the U.S. at No. 37 on the "Billboard" Hot 100 chart in 1981 and was No. 51 on Billboard's Top Tracks chart, which debuted in March 1981.
 "Back in Black" received the RIAA's Master Ringtone Sales Award (Gold and Platinum) in 2006 and reached 2× Platinum status in 2007.
"Fly, Robin, Fly" is a song by German disco group Silver Convention from their debut studio album "Save Me" (1975).
 Sylvester Levay and Stephan Prager wrote the song, and the latter produced it.
 "Fly, Robin, Fly" was released as the third single from "Save Me" in September 1975, peaking at number one on the United States "Billboard" Hot 100.
 Thanks to the success of "Fly, Robin, Fly", Silver Convention became the first German act to have a number one song on the American music charts.
