See photos these are the exact items you are purchasing.  

I can't quite figure out what these are.  It's collection put together by Lou & Glad.  These are amateur records but the amateurs appear to have some sort of access to higher end equipment.  The 2 of them are clearly putting on a scripted performance, but I can't imagine it being available for broadcast.  Perhaps a couple made some demo albums for voice work?  They make references to a "Bud" who we never see.  

 Don't get excited by the names Lou & Bud - these voices are not related to Abbott & Costello.  

There are references to driving in California and to Pasadena.  

This could be a fun mystery for an audio sleuth to solve.  Who were these people and why did they record all this?
