A whole lotta talent in this 1955 photo (from Jim Hilmar's FB feed).
From left to right: Jerry Byrd ( lap steel (Trotmore?), Chet Atkins ( Gretsch 6120), Wanda Jackson (strumming her flattop acoustic) and Tommy Jackson (bowing the fiddle).
I guess maybe Kitty Wells died her hair and borrowed Wanda Jackson's guitar. No mystery here. You can clearly read the name Wanda Jackson on the guitar in the first picture just by doing a simple zoom. I'm pretty sure that's Grady Martin on guitar and Pete Drake on steel and Jerry Rivers on fiddle though lol.
I'm in agreement with Erv, I think it's Wanda Jackson. She did a lot of shows in the 1950s and many with Hank Thompson in Oklahoma on early Television in Oklahoma City. I've seen clips of her and I think this is her.
I was just playing some Hawaiian steel guitar with my friend Johnny Green, when he told me about putting a band together here in Australia, for Wanda Jackson about 10 years ago. His son Hank played guitar in the band, but he's right into Hawaiian steel now.
