Sounds Of Solid Gold
  These were fully sequenced radio programming blocks submitted to   stations 
to use during their fringe-hours with free programming for them and 
free publicity for your local  USMC recruiting center.
Each box contained numerous LPs (this one has 13) with each LP 
  focusing on a certain year with the programs running about 15 minutes.  
DJ Marv Brooks who  started WMOD-FM, an oldies radio station  created these  
  weekly nationally syndicated public service radio programs 
  for the Marine Corps beginning in 1969.
There was also programs of "Sounds of Solid Country" 
  and "Sounds of Solid Soul".
I believe these continued through the 80's with over 50 volumes produced.
The LPs are blank on the back.
Volume 1
  Program 13: 1967
Marv mentions that this single was at the top of the charts at the beginning of the year, 
   held that position for  7 weeks, and said "Last Train To Clarksville" was  also #1.
