I remember singing a version of "Stodola Pumpa" as a boy. I must have learned it in school, because I can't think of where else I might have learned it (Cub Scouts, maybe, but I don't think so.)

All I remember of the first lines is

Walking at night, [something, something] summer air
[something, something, something ... something] maiden fair

Can't remember if it was "amidst the summer air" or "all in the summer air" or some other variation. I also don't remember if the second line began with a repeat of "walking at night ..." or something else.

If it is a Czech song, then there are probably a multitude of English translations floating around.
