Dream Valley Boys of Hanover; WORK & WBAL Radio Artists

While attending the Lancaster Family History Conference last month, one of the vendors had this promotional photo of the Dream Valley Boy’s of Hanover PA. I purchased the photo; wondering if I could discover the names of the men in the group for a YorksPast post.
The photo includes the names of the players as: “Little Mary”, “Mac”, “Bob”, and “Bill”. The back of the photo notes they are all former WORK & WBAL Radio Artists. The back of the photo also has a “Hoffman Studio, Hanover, PA” imprint. This was the studio of Adam A. Hoffman and was in existence from 1920 to 1950.
This Thomasville Inn ad, from The Evening Sun of Hanover, is one of several that have “The Dream Valley Boys” performing Saturday Nights during November and December of 1954. Those are the latest ads that I’ve discovered for this group; that featured: banjos, guitar, washboard, jug, and other instruments. Do any of my readers have memories of seeing this group perform?
This Valley View Grove ad is from The Gazette and Daily during 1938. Dream Valley Boys from Hanover, were giving free shows Sunday afternoon and evening on August 14th. Valley View Grove is more widely known by the later name Valley View Park; located on the hillside between Hellam and Yorkana.
The earliest mention that has been discovered about the Dream Valley Boys appears in the August 12, 1937 edition of The Evening Sun of Hanover; where the Ladies’ Aid Society of St. Luke’s Church held their annual picnic, with entertainment furnished by the Dream Valley Boys. The group’s performances spanned at least 1937 through 1954.
The following is a scan of the writing on the back of the promotional photo. I was not successful in putting names to the faces; can any of my readers help?
