Found the following quote from Andrew Eldritch, lead singer of electric/goth/rock group "The Sisters of Mercy", on the band's website (http://www.the-sisters-of-mercy.com/...ng.htm#softsae):
"Current desktop OS: Debian Linux.
Gentoo is sexy, but, having a slew of disparate machines, I've gone back to Debian.
Knoppix [Debian Linux] is the International Rescue of the computing world, and the
Kanotix [Debian Linux] installer was particularly friendly to my latest touring laptop."
In fact, the website has a suprising amount of information about the various computers and operating systems Eldritch and other band members have used over the years (as well as technical specifications for the various incarnations of the band's drum-machine "Doktor Avalanche").
