That's a really good interpretation. I still find it odd. Once we reach a "certain age" (cough, cough), we all look back at things we said, did, etc., at different points in our lives. And while we might cringe in certain instances, the reality is that history is not revisionist, i.e., we acted in a way that was consistent with who we were at that point in our lives. That doesn't make it any less valuable and shouldn't be looked down at as who we are today is the cumulative sum of those experiences. That's way too off-topic lol.
I think that's a really valuable lesson, yes. But there's a difference between recognizing the value of what was done in the past, and reliving what you've done in the past by hanging out with it every night.
I certainly know that my first marriage and subsequent divorce contributed to who I am today (and hopefully helped make me a better husband this second time around). But I have no interest in hanging out with my ex-wife. Similarly, I'm sure the band can see the way certain songs were really influential in their growth as artists and as a band. But that doesn't mean they have any desire to play some of those songs ever again. And I don't blame them for that.
