"Necessary Evil" lyrics

So I tried hard to be good, and do the things I should
I give up everything that I enjoyed
But if you slip a bit and your heart says, 'this is it'
That's a necessary evil, my boy

All my friends say I'm a fool and I won't break any rules
Why all the saintly virtues I employ
But if the slightest fling makes your soul begin to sing
That's a necessary evil, my boy

Well a man sometime has to sip a drink
And cast his eyes on a lovely shape
Then sometimes a wager desires
If a man says he don't, he's not a man he's a liar

So don't let yourself be sad
If what looks good is bad
Reach out accept the things that bring you joy
And so you feel inclined, it will help to keep in mind
That's a necessary evil, my boy

For a man sometime has to sip of the grape
Or cast his eye on a lovely shape
And then sometimes a wager desire
If a man says he don't, he's not a man he's a liar

So don't let yourself be sad
If what looks good is bad
I'll reach out accept the things that bring you joy
A man has got to live
Even stealers make you give
That's a necessary evil my boy
