Following up on my observation from the 2006 Dubliners concert at Vicar

A few months ago, I posted on here (which got deleted) about how there was one audience member from the Dubliners 2006 Vicar Street concert that caught my attention and how I noticed that he was one of the only ones that wasn't clapping along to Barney's banjo medley. Therefore, I wanted to know what the reason was for this.

Several of you commented that what I discussed was strange, and you're all right that this is strange. Even though it is strange that I want to know why this one audience member wasn't clapping along, this is something that I want to resolve because this wasn't a case where only half the audience was clapping along, this was a case where this guy was one of only about ten to fifteen audience members total that wasn't clapping along at any point during the medley.

Finally, I'm on the autism spectrum. Hopefully, that will give you all a better understanding to why I want to resolve this issue despite how strange it is. With that said, if you all feel that there are better ways I could resolve this matter as opposed to doing it through this subreddit, please let me know and I'll pursue those options.
