Exactly. I don't think it's likely he went to a gig. Brighton is a maybe, but that begs the question why? No pride events were going on. The fact that he might be gay is only a speculation and there's more evidence to point that he didn't have interest in romance. Maybe he wanted to see the beach, but there are beaches closer to Doncaster like in Hull. Why Brighton Beach?Unless he didn’t want to be tracked to his final destination, Brighton or otherwise.
His interests were pretty mainstream for the rock world. There really weren’t any gigs happening in London that night for bands he liked. None that he would’ve been willing to put his family through hell for, I wouldn’t think.
