Question

How does the theme of gang enhance your understanding of this passage?

“When you’re a Jet,
You’re a Jet all the way
From your first cigarette
To your last dyin’ day.
When you’re a Jet,
If the spit hits the fan,
You got brothers around,
You’re a family man!
You’re never alone,
You’re never disconnected!
You’re home with your own-
When company’s expected,
You ‘re well protected!
Then you are set
With a capital J,
Which you’ll never forget.
Till! They cart you away.
You stay
A jet!
