I'm looking for the words to a Czech song called "Rybák" (The fisherman). It's a lively song in 6/8 time (seems to switch between 3+3 and 2+2+2) which starts "Já jsem ten rybák" (I am the fisherman), or it might be Slovak: "Já som...". The recording I have is not good, so it's difficult for me to pick out much more than that, except I seem to hear "lodičku" (little boat) and "lovit" (to catch). None of the various search variants I've tried have turned up a ghost of this song.

I know it's a long shot, but can someone help?

I'd also like to find a Moravian song which begins "Horela, horela, hora javorová". I managed to find one mention of this in Google Books, in an index of Czech literature from about 1908, but nothing more of the song.
