"Seven Deadly Sins" recorded by The Dubliners. (I've thought about learning it for years.) I'll have to look up which LP it's on.

SEVEN DEADLY SINS
(from the Dubliners)

Some say that kissing's a sin
But tell me, how can that be true?
For kissing has been in this world
Since the very first day there was two.

Chorus:
Now if it wasn't legal
Then the lawyers they would sue.
And the prisons would be full of folk
Who'd had a kiss or two.
And if they didn't like it
Then away the girls would run.
And if it wasn't plenty
Then the poor folk would get none.

Some say that gambling's a sin
But I'll bet you 15 to 1
That gambling has been in this world
Since horses and greyhounds could run.
(Chorus) Who'd had a bet or two.

Some say that swearing's a sin
But where is the man that can tell.
For swearing has been in this world
Since the devil was told, "Go to hell!"
(Chorus) Who had a curse or two.

Some say that smoking's a sin
But a pipe now and then is enough.
But smoking has been in this world
Since Adam taught Eve how to puff.
(Chorus) Who had a smoke or two.

Some say that drinking's a sin
But a gargle is fine now and then.
For drinking has been in this world
Forever and ever, amen.
(Chorus) Who had a drink or two.
