>>318152Your mention of self-memorialization reminds me of something I thought about a while back that I think is a good example. Let's take the song Old Time Rock & Roll by Bob Seger. Just listen to the lyrics if you've somehow never heard it.
Hearing it today, the song might make sense in some way, but this is a song that was released in 1979. So what "old time" music is he referring to in the song? Bob Seger was born in 1945, so I think it's safe to assume we're talking about music from the 1950s, which would also be a normal starting place for considering early rock and roll as a genre. Elvis's career began around 1954 so we'll just use that.
So we have a song released in 1979 about music from around 1954 or so, that's a 25 year difference. This would be similar to if someone wrote a song about Linkin Park or Eminem or some shit, calling them "old time" music from the "days of old" enjoyed only by "relics" (not an insult, but a brag about oneself), contrasted with the soulless music of today.
After I realized this, the Bob Seger song became completely absurd. It's like an extreme degree of self-fellation of your own generation. That's how it seems to me at least. Deliberately turning your childhood into a cultural "landmark" of sorts. Probably no one at the time thought anything of it since baby boomers are too far up their own asses, and later generations just incorporate it into the mythology of the sacred "boomer childhood" immortalized in many other depictions of the 50s, etc.
Take pic related as another example? "Where were you in '62?" asks the poster of a film released in 1973, only 11 years later. Where were you in 2014? I think current generations, even if they're fond of their own nostalgia, aren't anywhere near as shameless as this.
