I am too thick to work out which Joseph I'm being compared to but most of them are wrong un's Barton, Stalin, Goebbels etc so I can't see it's a good thing!
To your main point I think when older folks play their original material it is often either hugely enjoyable in a "rage rage against the dying of the light" kind of way or basically a bit dispiriting . It's a minority of the time where one of those two things don't come into it at all and the age of either music and performer are irrelevant, especially in rock or pop. I don't know the dynamics of the original performances of these songs but in this case i don't get a sense of either of those two extremes - just a relatable band in terms of age (to me) playing their songs.
The carpenter one?
Guess it depends on how 'young' the music is at the time.
