This was so long ago, I can't remember the year!
Members of Shadowmusic, worldwide, organised and played a 24 hour, round the world, Shadathon, where every hour was allocated to a different club around the world to play continuous Shads music before handing over to the next. And it worked! For a solid 24 hours, somewhere in the world, live Shadows music was being played.
Quite an achievement.
