Alan,
I'm so, so sorry to hear of your wife's passing. You were so devoted to her, your love shone from every single character/letter you wrote on this forum, about her. I'm sure that she's listening from on high, and watching over you.
The track is so beautiful. A worthy tribute, I feel. It just soars. Just like a bird does.
The flute stands out in particular, for me.
Beautiful, beautiful song. Stay strong, friend.
