The song asks us:
"Who can retell the things that befell us, who can count them? In every age a hero or sage came to our aid."
The next stanza cites a specific example: "At this time of year in days of yore, Maccabees the Temple did restore", and so on.
I love this song because it is so easily altered for other contexts. For example, those of us who are new urbanists could write something like this:
Who can retell the things that befell us, who can count them?
In every age a hero or sage came to our aid.
In New York in days of yore, the city wanted to make the Village into one big road;
Jane Jacobs stopped his plans and taught us all, that the city was no longer just for cars.
Who can retell... [repeated]
Feel free to improve this- or better yet add additional stanzas!
