Here's how Hoyt Axton sang it:

RUSTY OLD HALO
(Bob Merrill)

I know a man a rich as a king
Still he just won't give his neighbours a thing
He'll get to heaven someday, I'll bet
He'll get up to heaven and here's what he'll get

A rusty old halo
Skinny white cloud
Second hand wings full of patches
A rusty old halo
Skinny white cloud
Robe that's so woolly it scratches

Some people have them big fancy cars
Swimming pools, fur coats and diamonds in jars
Real silver gates, real golden doors
They'll get up to heaven and trade them all for

A rusty old halo
Skinny white cloud
Second hand wings full of patches
A rusty old halo
Skinny white cloud
Robe that's so woolly it scratches

While you're on earth
You should shine like a star
Brighten up the corner wherever you are
Doin' each day the best you can do
The way you're sure that they'll never hand you

A rusty old halo
Skinny white cloud
Second hand wings full of patches
A rusty old halo
Skinny white cloud
Robe that's so woolly it scratches
