What a good idea!
Since tomorrow is the 12th of December, or 21/12, some bright spark came up with the idea of making it International Rush Day. (It's like 2112 - see what they did there?)
I'm not sure that I'll get away with wearing a Rush t-shirt at work but I'll have to wear one at some point tomorrow.
And hopefully the Rock Radio stations will pick it up too and play plenty of Rush throughout the day.
