Exit Elvis (the flaws of non contradiction) is the first, and currently only, album by Tribe Of Judah.
 It was the first full-length album by Gary Cherone after leaving Van Halen.
Moon Hee-joon (; or spelled Moon Hee-jun; born March 14, 1978) is a South Korean pop-rock singer-songwriter signed under SidusHQ.
 He initially rose to fame as the leader of former boy band H.O.T. under SM Entertainment.
Ray Danniels is a Canadian music executive, record producer, and talent manager.
 He's the founder of SRO (Standing Room Only) Management group, as well as independent record labels Moon Records and Anthem Records.
 He first rose to prominence as the manager of the Canadian band Rush and later served as the manager of Extreme and Van Halen.
 His sister-in-law Kelly Carter was married to Alex Van Halen.
 He was instrumental in bringing in Gary Cherone, former lead singer of Extreme, to replace Sammy Hagar as lead singer of Van Halen.
"More Than Words" is a ballad written and originally performed by American rock band Extreme.
 It is built around acoustic guitar work by Nuno Bettencourt and the vocals of Gary Cherone (with harmony vocals from Bettencourt).
 Released in 1990 on the album "Pornograffitti", the song is a detour from the funk metal style that permeates the band's records.
 As such, it has often been described as "a blessing and a curse" due to its overwhelming success and recognition worldwide, but the band ultimately embraced it and plays it on every show.
The Best of Both Worlds is the second greatest hits album by American hard rock band Van Halen, released on July 20, 2004 on Warner Bros. The compilation features material recorded with lead vocalists David Lee Roth and Sammy Hagar; omitting Gary Cherone's three-year tenure with the band.
 Prior to "The Best of Both Worlds"' release, Hagar reunited with Van Halen, and the band subsequently recorded three new tracks to include on the release.
The III Tour was a 1998 concert tour by hard rock band Van Halen.
 It was the band's first and only tour with vocalist Gary Cherone, in support of the only album he recorded with the band, 1998's Van Halen III.
100 People, 100 Songs () was a 2014 South Korean singing competition program presented by Kim Sung-joo, Jang Yun-jeong and Moon Hee-joon.
 It aired on JTBC from October 31, 2014 to September 27, 2015.
Tribe of Judah is Gary Cherone's post-Van Halen band featuring a couple of former members of Extreme (bassist Pat Badger and drummer Mike Mangini).
 An eponymous EP was released in 2001 and a full-length album was released in late 2002.
 Tribe of Judah is different from Cherone's other work as it features a more industrial/electronic sound.
 At least one song, "Left for Dead", was (supposedly) slated to be a track on a follow-up Van Halen album which would have featured Cherone.
Gary Francis Caine Cherone ( ; born July 26, 1961) is an American rock singer and songwriter.
 He is best known for his work as the lead vocalist of the Boston rock group Extreme, as well as his short stint as the lead vocalist for Van Halen on their 11th album "Van Halen III" and subsequent tour.
 In recent years he has released solo recordings.
 In 2007, he reunited with Extreme.
Van Halen III is the eleventh studio album by American rock band Van Halen, released on March 17, 1998 by Warner Bros.
 Records.
 Produced by Mike Post and Eddie Van Halen, it is the band's only studio album to feature lead vocalist Gary Cherone, and the last to feature bass guitarist Michael Anthony before he was replaced in the band by Eddie's son Wolfgang in 2006.
 Work on a follow-up album with Cherone commenced in 1999, but never advanced past a few demos.
