Colin, is The Girl in the Lake a Mickiewicz setting? I know that R-K wrote a cantata to the words of Świtezianka but haven't been able to discover its exact title. I'd very much like to hear that piece......
Sorry, Maciek, I completely missed your question

I apologise!
Yes...the cd notes say that "In 1897, just after finishing his opera 'Sadko', he(R-K) returned to Lev Mey's poem after Mickiewicz
Switezianka(The Girl in the Lake), whose first lines he had already set in 1862 in a song of the same title(op. 7 no.3)-the song's main theme, incidentally, recurs in the cantata."
I shall upload the Cantata later for you, sir
