(I was amused when gregmce did his list and had "Linus and Lucy" as his final song on the list. That's probably the only exception that I make to my music classification rule. To me, it's NOT a Christmas song and thus gets stuffed in with my regular music and not in with my holiday songs. Go figure.)
Today's song is not a Christmas (or Hanukkah or solstice, etc) song, but one about the changing seasons. I was looking for a Christmas album that was guitar instrumental and purchased Craig Chaquico's Holiday, sound unheard (like "sight unseen," only musical). Although the album wasn't quite what I was looking for, it had a piece called "Nonesuch/Ladies' Bramzel," which featured a children's choir doing a round. This piece quickly became one of the Christmas Songs that I Love despite not being a Christmas song.
