I saw the dance as a vision of ineffable power. A man could, with dignity and a towering majesty, dance. Not mince, cavort, do “fancy dancing” or “showoff” steps. No: Dance as Michelangelo’s visions dance and as the music of Bach dances.

Calling Ideas for May 8, 2012

This is:

Have a Coke® Day
Have A Coke® Day celebrates coke drinking, I guess.

I gotta admit if there hadn't been a recent singing call version of "I'd Like to Teach the World to Sing" (aka "I'd like to buy the world a coke"), I probably wouldn't be noting this as a day worth celebrating. Here's what I said last November, when the singing call record was released. But I lied; I said I wouldn't do the song, and I have (and I might even do it again on May 8).

This page of Coke® Slogans might give you some ideas for today. On the other hand, you may decide you don't want to further Coca Cola's dominance in our culture (but beware: a teenager was suspended from school for wearing a Pepsi shirt on Coke day...of course, the suspension was later removed from his record.
