Lyric discussion by singleeye 

I always thought of the book "Hawaii" when I heard this song. The longer boats were the white man coming to their islands. The parson was the religious "missionary" come to convert and takes advantage of the innocence of the young girls (Mary) or converts because they trust him. "I don't want no god on my lawn" was always an adversion to religion and all it's outward forms while his wanting just a flower he can help along was his longing for the truth, the truly good. I heard about the UFO thing but it just doesn't say that to me at all.

As the guys below say, the UFO thing was a joke. But perhaps it was not a completely pointless joke. This song is a rejection of religion; perhaps the UFO comment was a mocking comparison between the beliefs of many traditionally religious folk, and the beliefs of people who think they've been abducted by aliens.
