Boy, You're Gonna Carry That Weight a Long, Long Time

I've always assumed Carry That Weight was Paul McCartney (rather astutely for a 26 year-old) warning his fellow Beatles of the burden that will come for each of them once they're no longer Beatles & have to try to live up to their own legacy, and I'm pretty sure that's 100% true, but just now it's occurred to me for the first time that it can also be applied to whoever will end up being the last surviving Beatle and now I'm totally bummed out. 😢
