The song says that in Heaven, there is no beer.
There’s wine and whiskey and ouzo, and pretty much everything else, but there is no beer.
You can’t even smuggle it in. The angels will catch you and confiscate the beer.
Do the angels drink it?
No, they pour it out in the street.
That’s why we sneak out at night.
There are a bunch of breweries and bars right outside the gates of Heaven.
And because we’re already on the list, we can get back in again.
Even though St. Peter always goes “You look familiar.”
And he winks.
