Just out of interest I went back to You Tube ... there are an awful lot of clips of Florence on there, one quite interesting one about her accompanists (Cosme McMoon among them), and would you believe it, one about a play about her = "Glorious" .... way to go for WAV??
Seriously though, as you've been told many times before, David, you would be best advised to seek some advice and tuition from a decent singing coach. It sounds to me as though you possibly have the makings of a pleasant voice BUT your sense of pitch, breath support and rhythm are all seriously lacking. I don't think that there's anything there that couldn't be at least partially cured or assisted with a lot of hard work both from a teacher and from you... but at the moment it just ain't got it.... sorry.
