I am not a subscriber and was able to access it earlier.
A work around may be googling the title of the article.
This is quite a comprehensive article on this monumental show. I lived very close, in neighboring Shrewsbury, and was 14 years old when I heard the ticket/show announcement on the radio in the morning waking up for school. Still have the local newspapers from the next morning.
The security guard/bouncer also casually mentions that there may be a tape of the show.
