I still don't know for sure what key "Be Glad" is in, so I left my notation in C major, resulting in a slew of accidentals:
The lyrics here are:
Long was the summer
Torn from the spring
Deep were the days of your longing
Now you are risen
Free as the wind
Watch as your woman is dancing
The melody for the "Now you are risen..." section is essentially the same as the melody for the "Long was the summer..." section. The significant difference is that it's raised a half step, so between the two, there's a musical sense of having "risen."
