GUEST,KS has it right.

Remember, Chris Hillman is as much this song's writer as Gram Parsons.

1968 was a important year for both of them, with Sweethart of the Rodeo being recorded early that year and the first Burrito Brothers record being worked on late the same year.

Also a big year for social unrest, rock concerts, drugs and more. The man who died was Bobby Kennedy who was shot in Los Angeles in June. Much of the rock community supported Kennedy.
