The Gravedigger's Song

"Come Out and Play" is a song by the Californian punk rock group The Offspring.
 It is the seventh track on their third album "Smash" (1994) and was released as the first single from that album.
 Written by frontman Dexter Holland, the song was the second single to be released by the band, after "I'll Be Waiting" (1986).
 It is considered to be The Offspring's breakthrough song, as it received widespread radio play and reached number one on the "Billboard" Modern Rock Tracks chart, bringing both the band and the punk rock genre to widespread attention.
 Inspiration for the "keep 'em separated" lyric came from Dexter Holland's experience in a laboratory cooling Erlenmeyer flasks full of hot liquids.

The Gutter Twins is a musical collaboration between rock musicians Greg Dulli and Mark Lanegan.
 Dulli and Lanegan have regularly contributed to each other's projects since 2000, most notably in Dulli's Twilight Singers; of the duo's origins, Dulli said "I think Mark told a journalist we were doing it, and then the journalist called me, and I didn't know we were doing it."
 On Christmas Day 2003, Dulli and Lanegan began work on the collaboration.
 Their name is a punning homage to The Glimmer Twins, the pseudonym used by Mick Jagger and Keith Richards for work producing recordings by The Rolling Stones.
