I'm looking for the length in minutes that the average rock concert lasts. Ideally this would be an industry average derived from a large sample. I will take a figure for any decade in the last 30 years. I will pay an extra $25 for any additional data point in a different decade (1970s and later) but no more than one point per decade.
Note: This question is part of a larger series. I'm posting several additional questions similar to this one. Please see this earlier question (which is still open, as of this posting) for additional background: http://uclue.com/?xq=4298
