"I'm a high life flyer and a rainbow rider."

"I'm a high life flyer and a rainbow rider." Three Dog Night -Joy to the world- I don't really understand this quote but I'll give it a good shot at it. Maybe this quote has a hidden meaning to it. Maybe high life flyer means that the person is rich and spends a lot of money and has the wonderful life. But he's a rainbow rider and, which could mean he's gay and people dont except him into society. Which again is not right at all but thats life people are dumb sometimes. I have no clue on how to disect this quote at all. Another possible shot at this could be a person who is a free bird sorta like a hippiee and they just live day by day to the fullest potential that they can give. Another shot at this quote could be a guy in an air plane riding in it and hes riding on the rainbows since they're up in the skies. I don't like this shot very much but you never know.
