I’ve just found another Cezchoslovak star of the 60s/70s/bit of the 80s!..
… Naděžda Urbánková…
I think she was just a little bit older than the one who performed the English version of this tune, which you might just about recognise. (I’m afraid!)
How does a song performed by a probably not-yet-teenage boy get covered by a woman in her mid-thirties? Mimořádne!
