Saw a great documentary about him some years ago.

probably brewed some. Along with some elderberry wine. They loved accordions, too. My grandfather brought one with him when he emigrated from Germany, and my youngest aunt owned a few, including one that had once belonged to Lawrence Welk. My very early childhood memories include keggers on my grandfather's farm, lots of relatives there (including one great-aunt who was a nun), and lots of music.

The original German version of that song was written for this scene in a 1956 German film:

The banquet hall where I worked in HS & college used to have polka bands on Sunday evenings in the summer.
He'd be there with his band early in the summer then near the end.
We'd have the kitchen open making fried chicken & French fries.
One of those times we about to run out of chicken, so I had to run to a supermarket and buy a dozen or so whole birds.
I get back and the band is on break. Frankie tells me he'll help out. So he starts piecing out the birds.
Turns out he was trained as a butcher! He got all those birds done in the amount of time I could have done 2; maybe.
There's my Frankie Yankovic story!

... my partner and I covered with a couple of others. I was in the kitchen cleaning up for pack out and he walked into the kitchen because the food had taken down before he got there. I made him a plate and we talked for about five minutes. Don't remember what talked about except it was just light conversation.

At another function, the hostess went to my partner and told him to get that ofay fucker out of her party. I said yes ma'am and split.
