Further Update (and bumped again):

If you’d like to know what they’re singing, a kind Buttle’s World reader tracked down the lyrics. In fact, here’s a link to the whole story of the song. And here’s that swell dancer. Corrected Czech lyrics below.

Jedu takhle tábořit škodou sto na Oravu.

Spěchám, proto riskuji, projíždím přes Moravu.

Řádí tam to strašidlo, vystupuje z bažin,

žere hlavně Pražáky, jmenuje se Jožin.

Jožin z bažin močálem se plíží,

Jožin z bažin k vesnici se blíží,

Jožin z bažin už si zuby brousí,

Jožin z bažin kouše, saje, rdousí.

Na Jožina z bažin, koho by to napadlo,

platí jen a pouze práškovací letadlo.

Projížděl jsem dědinou cestou na Vizovice.

Přivítal mě předseda, řek mi u slivovice:

«Živého či mrtvého Jožina kdo přivede,

tomu já dám za ženu dceru a půl JZD.»

Jožin z bažin… itd.

Říkám: «Dej mi, předsedo, letadlo a prášek,

Jožina ti přivedu, nevidím v tom háček.»

Předseda mi vyhověl, ráno jsem se vznesl,

na Jožina z letadla prášek pěkně klesl.

Jožin z bažin už je celý bílý,

Jožin z bažin z močálu ven pílí,

Jožin z bažin dostal se na kámen,

Jožin z bažin tady je s ním amen.

Jožina jsem dohnal, už ho držím, johohó,

dobré každé lóvé, prodám já ho do ZOO.

Pretty hilarious, eh? Oh, in English? Here you go:

I’m driving in a Skoda 100 to camp in Orava
Because I’m in a hurry, I risk crossing Moravia
A monster prowls around there, it comes out of the swamp
It mainly eats people from Prague, and it’s called Joe

Joe Swamp creeps through the bogs
Joe Swamp approaches the village
Joe Swamp is sharpening his teeth
Joe Swamp bites and strangles
Who’dve thought that the way to deal with Joe Swamp
The only thing that works is a plane with white powder

I was driving through a village on the road to Vizovice
I met the village elder who told me over some slivovice
“Whoever brings me Joe, dead or alive,
Shall have my daughter and half the collective farm”

Joe Swamp creeps through the bogs
Joe Swamp approaches the village
Joe Swamp is sharpening his teeth
Joe Swamp bites and strangles
Who’dve thought that the way to deal with Joe Swamp
The only thing that works is a plane with white powder

I say, “Chief, give me the plane and the powder
I’ll give you Joe, no problem”
The Elder agreed, and at dawn I rose to the skies
The powder fell beautifully from the plane onto Joe

Joe Swamp is now all white
Joe Swamp escapes from the bogs
Joe Swamp has turned to stone
For Joe Swamp, this is the end
I caught Joe and now I have him, woohoo!
Cash is always good so now I’m selling him to the zoo

Prefer it with subtitles?

Apparently the song was also a hit with Russian Animators. I guess they couldn’t afford crop dusters.

You have now been quite thoroughly Czech Rolled.

Bleg:

What is that instrument being played by the bearded man at the piano, the first one on screen, called?
