...also a cousin to Jimmy Swaggart...
My thought when I read this as well. Fortunately I scrolled down enough to see that you beat me to it.
“..also a cousin to Jimmy Swaggart...”
Also Jerry Lee Lewis.
Of the 3 and strictly thinking of just music, I like Swaggart the best something about that Boggie Woggie Gospel sound.
I think they are all related to Ronnie Milsap, also.
