Gary ... For the life of me I can't believe that you and Fran couldn't understand a word she said ... maybe the bad mix was coming from your speakers ...
I'm 77 years of age, have a hearing loss in my right ear due to a lifelong punctured ear drum, and I understood every word ...

As I responded to Fran. liking or not liking her vocals is subjective, but not understanding them ?!! ... that's a whole different issue ...

PS: as for understanding the older songs, the fact that we know them helps a lot ...
