There was indeed coverage of the tour as part of the work session tape of that year (remember those?).
Lillian Padilla gave a very good on-camera tour of the store, and of course Earl was the host of the rest of the trip.
And somewhere near Lumberton there are to this day some 3/4" tapes that got flailed when I discovered ants crawling all over me.
Earl and Carmen we gracious to re-do some of the tour for me.
It was some pretty interesting stuff, as the 492 rock is still there etc.
Ah, the old times.
