Ha ha, Knopfler is just a talker... you could make the same case for Johnny Cash, Bruce Springsteen, Billy Joel, Bob Dylan... he’s in good company.
@dwcda yep, in fact, i was just talking like Knopfler and Cash in the shower a half hour ago (no aptitude required).
Here are some bros who can actually sing. The recordings may not be "audiophile" enough for the gon crew, but, nevertheless, it is the voices of these type of bros that the lasses fall for. Lasses are not attracted to talkers (unless they get rich).
Poppy Bros
George Michael - Father Figure
Michael Bolton - Said i loved you but i lied
Rocky Bros
Geoff Tate (Queensryche) - Silent Lucidity
Geoff Tate (Queensryche) - Della Brown
David Coverdale (Whitesnake) - Is this love
David Coverdale - Sailing Ships
Bruce Dickinson (Iron Maiden) - Tears of a Dragon
etc, etc, etc
and my personal favorite bro, of course (might be a very complicated voice for some of y’all)
