I saw this today. I didn’t see news about David Ogden Spiers passing.
MASH was one of those long running TV shows that I didn’t follow specifically or exclusively as a teen, but every time I saw it on I would sit and watch. Then when I enlisted in the Army and I’d be on shift working at my first duty assignment (Site-R), we’d all watch MASH whenever it came on. I didn’t think much of it at all. But years after the series ended, I found that hearing the theme song brought back a certain feeling of nostalgia and an unspecific sense of days gone by. I dunno, it’s hard to describe.
