Stopped by Carter's Vintage Guitars today and
Johnny Bellar was playing a resonator and sounding pretty good. Here's a video I shot of him (you MAY need to have FaceBook to view it - not sure about that).

Very friendly guy and obviously a great player. I'd not seen anyone play muted thumb Chet Atkins style on a square neck resonator before.
Here's a clip of him off YouTube playing Shenandoah (audio doesn't come on until 12 seconds into the video)
