The Salvation Army is Sal's or the Starvation Army. Just noticed this one, from the ongoing posts about thrift shops and their nicknames. I've always thought the "Starvation Army" bit, to be originally a tag from a hundred-odd years ago. In the all-but-war situation that obtained then, between militant secular socialists and militant evangelical Christians -- two groups with extremely different views of what was wrong in the world, and what to do about it; both parties made much use of music and song, and in the course of that, enthusiastically borrowed / stole from each other. If I recall rightly, "Starvation Army" comes in the song "Pie In The Sky" -- a socialist parody of the Christian "In The Sweet By-and-By".
That's where we got it! I love that song. (Nitpick: The actual title is "Preacher and the Slave"):
And the Starvation Army they play,
And they sing and they clap and they pray.
Till they get all your coin on the drum,
Then they tell you when you are on the bum:
If you fight hard for children and wife
Try to get something good in this life
You're a sinner and bad man, they tell,
When you die you will sure go to hell.
You will eat, by and by,
In that glorious land above the sky;
Work and pray, live on hay,
You'll get pie in the sky when you die. (That's a lie!)
