The song, Have you seen the rain ..gets me every time.
The song is about Fogerty’s brother and his return from Vietnam. He was spit on at the airport by anti-war protesters and John asked him if that upset him...his brother said “no, these people have never seen the rain.” Meaning that they weren’t there and they couldn’t possibly understand what he and his buddies went through. They shouldn’t judge him unless they had seen what he had.
It’s also been suggested that the lyrics are referencing the Vietnam War, with the “rain” being a metaphor for Napalm bombs falling from the sky.
