In England it’s not straightforward. Yes we drop a u for humorous and similar ous endings but not for all endings. For instance, we have words like honourable. favourite etc and flavorous but flavouring, flavourless, flavoursome and so on.

Well, Neil Young IS Canadian…
The “u” makes everything classy.

Not only BrE but also AmE. It is standard BrE to drop the “u” when spelling derivatives of words ending in “our”, e.g. humorist, rancorous.
Well, as Neil Young is Canadian, I would fully expect his spokesperson to spell it that way.
Oops, didn’t spot that Steve already made that point, sorry!
