Henry Paul of the Outlaws states:

“…there was an album out, the best of the Rolling Stones, called High Tides and Green Grass. That was the name of the Rolling Stones' greatest hits. This is like 1966. And I think it was a manifestation of that title turned in reverse, "Green Grass and High Tides.” I know that much. And I know that it was a song written for rock and roll illuminaries, from Janis Joplin to Jimi Hendrix, and it had nothing to do with marijuana. But it had to do with, I think, a specific person’s lyrical look at… “as kings and queens bow and play for you.” It’s about Jimi Hendrix and Janis Joplin. “Castles of stone, soul and glory.” A lot of it is just sort of a collage of words that really don’t have all that much to do with anything, they just fit and sounded right. But I have to say it’s one of my favorite lyrics. My songwriting is more Steinbeck, really rooted in accuracy and reality; that is definitely Alice In Wonderland."
