and the winner is...

Since there were no right answers to the quiz question (in fact, there were no answers at all), the prize goes to me. Which means I'll keep it to myself plus I'll keep it secret. No use guessing what it was, too late, so to speak.

But I won't be so nasty to keep the right answer to my own self, therefore, if you haven't googled that one yet, El Chombo's song is in "gibberish" (here you'll find the full wikipedia definition). I can only summarize that this is a nonsense language, a category which my 6-year old daughter tends to use when she wants to sound foreign, with only that difference that she calls her self-made language "hamburgerski" (hamburegrian?). It doesn not derive from the word "hamburger", as she's never eaten one in her lifetime and hopefully, she never will. Although, on the other hand, it's likely she's seen a McD commercial on tv.

On our first and only, so far, class with the FCE students, the topic of old devices was mentioned - like walkmans, for example. So, to continue on that topic, I myself remember another antique equipment: a tape recorder by Kasprzak, on which, as a child, I recorded my own songs in gibberish. "Babuleebes blow" was one of them. But it's another story.

so to speak - rzec by można

derive - wywodzić się
it's likely = it's very probable
first and only - pierwsza i jedyna
