And while I didn't mind the Cylon reveal at the end, I intensely disliked the "All Along the Watchtower" method. It just didn't feel right that not only do these four people—and only these four—hear this song, but that the song is one from Earth canon. It bothered me. (Here are the rest of my conflicted thoughts on the finale.)
That said, I kinda dug the cover, so I did a little digging into it and came across the site of Battlestar Galactica composer Bear McCreary, who rearranged the tune for the finale. And I came across a noteworthy nugget of information, among his details of the construction of the cover:
"I happened to catch Ron Moore in the hallway at Universal and, in a brief conversation, got everything I needed to know. I learned that the idea was not that Bob Dylan necessarily exists in the characters' universe, but that an artist on one of the colonies may have recorded a song with the exact same melody and lyrics. Perhaps this unknown performer and Dylan pulled inspiration from a common, ethereal source. Therefore, I was told to make no musical references to any 'Earthly' versions, Hendrix, Dylan or any others. The arrangement needed to sound like a pop song that belonged in the Galactica universe, not our own."Which sheds a little light. For the rest of McCreary's "Watchtower" tale, head on over.
