I guess it's possible that it was psychosomatic but notable that I was never too concerned about catching covid or stressed out about anything else at the time and I'm also one of those people who almost never gets headaches of any type. So I'll never know for sure but if I had to put money on it, I'd say I definitely had, though it obviously had a pretty mild effect.
"Ogden's" is a grower. I didn't like it much either when I first heard it and still have mixed feelings about the "Happiness Stan" story on side 2. But a lot of The Small Faces' other stuff on Immediate is just as good if not better than "Ogden's" even though that's their most popular album so maybe check out the "Darlings of Wapping Wharf Launderette" instead.
Hope you feel better soon brahski. Get that vax! I'm "team J&J" myself.
