"Except they're now all in their mid-50s. Is it even the original line-up? - or like just one original and some session musicians playing as "Human League". "
That's the thing. I used to love depeche mode back in the 80s n had a real thing for David Gahan in his vest n black leather pants. But cycle forward 20 years and I saw them on a show, Dave had gone through a really rough time with one thing and another but was still in his vest n leather pants n he had bingo wings (the flabby skin at the top of your arms) and did not look good, as he clapped the skin just sort of flapped and it was not pretty.
He does still sound good though even now, maybe just needs to realise he is not still 20.
Saying that though, last week I saw the Rolling Stones on something, and Mick jagger was there in HIS leather pants!!!! What is he?? 80???? 90?????? He was all over the place n still fit, but the face. Him and Keith Richards looked like spitting image puppets.
