Close your eyes and tell me who it is

I thought it was his dad singing

[Danny Mitchell]

I know, Ron, it's incredible. Don't know if you've heard 'Willie and The Boy's'? The three of them singing harmonies beautiful.
You can't beat sibling/family harmonies, they just seem to lock together. There's an English folky group called The Staves and their voices are so sweet and heavenly together. And who could forget the mighty Everly's .
