I was at a Robert Hunter show in the early 90s where he was razzing the crowd about the Eagles poor performance the previous Sunday. After the gig he was sitting around and I went up and asked if he was a 9ers fan. He gave me a big smile and told me he'd had season tickets for several years.
When I was in the music biz I got to deal with Dennis McNally a few times and I found him to be a very knowledgable fan.
And of course, it's well known that, although he lived in Colorado, Hunter Thompson -- a brilliant football analyst -- was primarily a 9ers fan for most of his life.
