Agreed, LitR. With the musical-performance-endings Lynch is offering/forcing us to take a moment to absorb, to relate what we've seen to what has gone before, to relate it to the way we find ourselves in the world, but he is also providing more, related content - verbal but with heightened emotion and thematic focus.

On the simplest level I take electricity to be energy/valence, good or bad, and darkness to be endings/finitude, whether of days, projects, relationships, persons, planets. So, what is left? Karma - the ongoing quest for the good life in a world where evil is an experiential reality, a part of our human makeup.  

Hauntingly beautiful.  It's tough because the moment that comes on, you know it's basically the end of the show, and you are kind of upset because you've waited all week and want there to be more, but as we sit here now, however many hours after viewing - if there's one thing from that entire episode that sticks with you it's that hauntingly beautiful song.

Beautiful ending with famous Rebekah del Rio...perfect fit after Log Lady's message: 'Electricity is humming.  You hear it in the mountains and rivers. You see it dance among the seas and stars and glowing around the moon, but in these days the glow is dying. What will be in the darkness that remains? '

Song is the answer.

And the zig-zag black and white dress, red curtains...left me speechless

Yup.  Perfect summary.  That dress and the curtains sure were an amazing coincidence, weren't they?  ?

A beautiful song sung by a very beautiful woman 🙂

Truly mesmerising. 

Loved the ending. But was very sad once it started as I knew the episode was about to end!
