Up above in 2013, a Mudcatter named 999 posted this link: https://www.question.com/who-wrote-the-song-easy-come-easy-go-through-94432.html. On that page, a poster named "Robo" (Roland Owens)(Patrick of "John and Patrick"?) said the song was written by his singing partner, John Rodak, who died March 30, 2014. But another poster on that page says the song was written by his father, Kevin Johansson, wrote the song in South Africa in the late 1960s or early 1970s.
Somebody else on that page posted alternate lyrics:

EASY COME EASY GO

easy come easy go through summer through snow
up and down all around this universe I go
and I'll walk upon your waters, move mountains from your path
with a smile from my companions. I'll teach you how to laugh

cause I have ripped off my mask, torn down my walls
strapped up my boots to answer his call
you say that i am a rover, got no place to call my own
with a thousand places I call home,I know i am not alone

I've thawed out my body, I've put blood in my viens
cause people were crying , they were calling out my name
you say that I am a poor man, got no one to care for me
With a million brothers and sisters , how rich can one man be?

my sister is from Boston, my brother rides the rails
my cousin is from china, my cousin brings the mail
I have met with kings who have passed away, but I know they still care
My Father lives in Heaven, Babe He's a millionaire

saw a light in your window, thought i would pause and take a rest
say helo and goodbye and wish you all the best
I am just here on a visit , I may not be back this way
cause when my journeys over I'll be going home to stay

--- I have a small retreat book with the words - hope to find it - the above is from internet excerpts. I would like to get the original words. Learned the song from TEC 12 - Teens Encounter Christ retreats in the Chicago area late 60's.
