Can You Identify the People in these Classic Sioux Falls Pictures?

Who are these people?

We received these photos of musicians in an early KSOO radio studio. They came from a person in Medford, Oregon.

Since there are no electric guitars in the photo we have surmised they are from before the mid-1950s. Are they local, regional, or national musicians?

We would love to know the identity of these folks.

If you have any information about any of them, please contact Beth Warden, KSOO News Director at  Beth@ksoo.com
