The song was co-written by famed songwriter Desmond Child, Ratt guitarist Warren DeMartini and lead singer Stephen Pearcy.

"Wanted Man' is the first track on American heavy metal band Ratt's album "Out of the Cellar".  It was also featured on the soundtrack for the 1985 film "Weird Science".  The song was composed by Robbin Crosby, Stephen Pearcy, and Joey Cristofanilli (who was briefly filling in for full-time Ratt bassist Juan Croucier), and it was the second biggest hit on the album (note: "Back for more" did not qualify for a chart position since it was not an actual single release), reaching number 87 on the "Billboard" Hot 100 and 38 on the "Billboard" Mainstream Rock Tracks chart. "Dance" is a song by American heavy metal band Ratt.  It is the first track off their 1986 album "Dancing Undercover" and the tenth track of their compilation album "Ratt & Roll 81-91".  It reached #59 on the Billboard Top 100.  The song was written by Stephen Pearcy, guitarists Robbin Crosby and Warren DeMartini, and album producer Beau Hill. "Eat Me Up Alive" is a song by American heavy metal band Ratt, the song was the second single off the bands 2010 album Infestation.  There is also a music video for the song along with Best of Me.  The song was written by Carlos Cavazo, Warren Demartini, and Stephen Pearcy for the team to have the song sound like it came out of 1984. Vicious Delite was an alternative metal band formed by Stephen Pearcy in 1995 after Arcade.  They released a limited self-titled EP in 1995 followed by a full-length album.  The members of Vicious Delite were Stephen Pearcy, Tony Marcus, Michael Andrews, and Rob Karras.  Stephen Pearcy was said to still be in his Ratt form, indeed his voice was just as compelling.  Though his look (shorter hair & no fancy clothes or makeup) was different, his on-stage and off-stage personality was still as exciting.  Mike Duda (of W.A.S.P.) would replace Andrews on bass, and was with Pearcy handing out demo CDs just a few weeks after the band's formation.  Their first live performance was intense & wonderfully surprising.  Pearcy still had it in all the right ways needed for a true rockstar and quality musician. "Slip of the Lip" is a song recorded by American heavy metal band Ratt in 1986 from the album "Dancing Undercover" and is also on their greatest hits album "Ratt & Roll 81-91".  It was written by Ratt vocalist Stephen Pearcy, bassist Juan Croucier, and guitarist Warren DeMartini. Alexander O'Neal (born November 15, 1953) is an American R&B singer, songwriter and arranger from Natchez, Mississippi.
