I am not a country fan, but Wanda Jackson from Maud, Ok. should be on the list. She put Rockabilly on the map, and was one of Elvis’s girlfriends.
ell, phooey! She wasn't on 'the list' I got the others from, so I'll post her picture here!
Thanks, CC - I'm not familiar with her name or her music, but sounds like she certainly should have been included.
