A Silesian folk tune

Is it possible that Handel knew the Silesian folk tune usually called the Crusaders’ Hymn? The tune is that old, but this was before composers were fond of adapting folk melodies into their compositions. In any case, here for your Easter listening, is my rendition of the Crusaders’ Hymn, or Fairest Lord Jesus, along with images of Spring, mostly from my neighborhood. I hope you enjoy the song, and I hope your day is a good one.
