U of Washington:
In my post #16 above, I may not have been clear.
Almost certainly, George Henderson at the Oakland A’s playoff series two weeks before U. of Washington.
Reviews of the videotapes of the series in 1981 show a wave being done in more than one inning.
In Germany, it’s “La Ola,” Spanish for “the wave,” and I’ve heard the story that it had been invented during the Mexico soccer World Cup, although now I realize this might just have been where it was first presented to an international audience.
It’s pretty popular at soccer games here, and I actually like it.
Meeko: You’re right about college sports not that common in Germany, nor are cheerleaders. Cheerleading, however, started to become more popular in German sports now, but mainly at events in sports imported from America, such as baseball; in professional soccer, for example, it happens from time to time, but it’s not common and certainly very marginal.
I love the wave. The heck is wrong with you people?
It would appear that the concert you attended was June 4, 1983.
