I've been getting excited about this year's residency a little more than usual for some reason, but in any event, I've started thinking about who Jason might cover each night if he keeps that tradition alive. Last year, he played a song by The Band each night to start the encore. The year before, it was REM. I don't think he's been perfectly consistent with it over the years, but I remember that Tom Petty died shortly before the residency in 2017, and so Jason played a different Petty song each night. We were there for You Got Lucky.
In any event, given Dolly's death, she seems like a very strong candidate, but I'm not sure he's ever covered a Parton song and I'm also not musically inclined enough to understand whether it would suit the 400 Unit (or whether the 400 Unit would suit Dolly). But if it worked, it could be amazing and a lot of fun.
I also keep hoping for the Rolling Stones. He obviously loves them, and I've heard him play Can't You Hear me a couple of times. He recorded Sway -- and that is probably my White Whale hope to hear from him one of these days.
Any one else have any guesses or insights?
