When you start drinking beer immediately after your last day of work for this year, you start to free-associate:1) Noiro = Blacky.
2) Noiro, spelled backwards, is orioN.
3) "Orion" is a most excellent Metallica tune, back when they were good.
4) "Orion" contains one of the best (and one of the last) bass solos by Cliff Burton.
5) Blacky plays bass.
6) Blacky shoudn't ride on a bus in northern Europe when there's ice on the road.
Thanx for listening, I feel much better for having gotten that out of my system. I'm going to go and have yet another beer now...
