I also notice that Immortality is not one of the possible tracks. And I was hoping for Yellow Ledbetter just so that we could find out what the lyrics are.
They are always semi-improv'd but with recurring themes / lines. Adds to the mystery of it all. During Ed's solo tour a fan asked what are the lyrics to YL and Eddie responded: 'Wait … you mean there’s lyrics?' He then expounded on the meaning at least:
He then proceeds to tell the story surrounding the lyrics, saying it was written around the time of the Gulf War when “Papa Bush” was President. He knew an “alternative-looking” friend from Seattle who received a “yellow letter” when his brother died in the war. Ed was walking with this friend and there was a flag hanging from a porch on a house along the road. When the friend acknowledged the flag patriotically, the people seemed to not reciprocate his homage (”but they don’t wave”) because of his appearance.
As I'd said earlier I'd prefer live versions, mainly because of the reasons Jonnyboy already stated. When playing live PJ extend solos, add / change lyrics, one of my favourite examples being in Yellow Ledbetter in a Melbourne show where Ed changed the 'boxer of the bag' line to:
"and mr. security man, i know ya just trying to do your job;
but we're all friends here, and we're about to leave for home'
after security were trying to grab this kid not far from me that was smoking.
And yes, Immortality would have been perfect for this.
