Plastic Jesus

When I saw my sister in Texas a couple of weeks ago, she started singing
this song.. All she remembers is :

"Well, I don't care if it rains or freezes,
Long as I got my plastic Jesus
Riding on the dashboard of my car"

*****

I think this is part of the 1st verse... am I right ????
Through the trials and tribulations,
We will travel every nation,
With my plastic Jesus I'll go far.

*******

I think this is the 2nd verse--

any body know the rest of this song ????

*****
I don't care if it's dark or scary
Long as I have magnetic Mary
Riding on the dashboard of my car
I feel I'm protected amply
I got the whole damn Holy Family
Riding on the dashboard of my car

*********

This song is making me crazy now ..

Who recorded this ???

Who wrote it ??
