The ending coda always brings a bit of a lump...
to my throat.
When we finally return to the presant and we see Billy as an old man and he says "You asked if I had scars, yes sir, I have my scars." and slowly turns and walks away with Alan Silvestri's music swelling up.
It feels like we're watching the sun setting on the life of this man who has seen and done more than any of us can imagine.
If you expect the unexpected doesn't the unexpected then become the expected?
