Kudos to 'slholzer' for doing the homework getting valuable information on these two sides.
I live in Grand Rapids, Michigan, just 30 minutes from Hastings and have recently found this 78 in my collection. I was fortunate to grab hundreds of 78's from a defunct AM radio station when they moved back in the early 70's. In the early 50's they had a daily Country show, so there are a lot of gems in the stuff I gathered, including a copy of this 78.
It seems obvious to me that this a private local Michigan release.
In fact, now, if you Google 'Tribute to Vernon Steenbock' you will get an entry/result ("Catalog of Copyright Entries") that shows that the composer of these tracks (Patty Demond) submitted them in November of 1954. The official title has it spelled "Vernon" not Vermon, so that proves that the odd spelling on the 78 label is simply a typo.
Since I'm about to turn 70 and am liquidating my collection, I will be putting this up for sale on Ebay in the near future.
I was able to locate news coverage on the accident at Newspapers.com. It appears that the north wall of the Steenbock Gravel Pit collapsed, trapping four men in the 85 foot deep pit. The pit was 600 by 200 feet and filled 8 feet deep at the south wall with suffocating fine-textured gravel. Death would have occurred within minutes of burial. Vernon, the first to be found, was upright against the pit's vertical wall. His body was partly decapitated by the pit's cable-mounted claw as they dug for it, so the already hopeless recovery effort proceeded thereafter with hand tools at some risk to the retrievers. Henry J. Steenbock and the fourth fatality, 24 year old truck driver Eddy Lewis, were found together. Roy's was the last body recovered. The cave-in was discovered by the widow Steenbock when she came to bring the family lunch.
These two sides are a piece of local history. Three members of the Steenbock family, father Henry J and his two sons, Vernon (not Vermon per the cemetery listings and references in surviving sister's 2013 obituary) and Roy, were killed in an accident at the Steenbock Gravel Pit in Hastings, Michigan on June 5, 1952. They are buried in the Riverside Cemetery in Hastings. It seems likely that Sally Massey and/or Patty Demond had some connection to the family, although I have no idea exactly what that connection was or how close it might have been. It might say a lot if the correct name really was Vermon and not Vernon.
