Last Saturday I went with a friend to Rotterdam to the Laurenskerk where there were two New Year concerts, at 15:00 and in the evening at 19:30 a 50-year jubilee concert by Peter Eilander. On my youtube channel I published a few Psalms that wer played and sung.
The concert of Peter Eilander started with an improvisation that triggered me, since the melody was kind of known by me. So I googled and asked around an found out what song it was. The Dutch title is "God zij met ons deze dag en nacht" So in the weekend I played without sheetmusic and arranged this version of the hymn.
