Various signatures on each "frame" (listed are the ones I could make out)
17th National Choral Conference performance
Mother's Day Concert with The Training Choir and The Apprentice Choir
Celebrating ABS 75th Anniversary
UCA - University of Central Arkansas
Program for the Annual National Conference of the Organization of American Kodaly Educators
No exact date listed for concert. Weird!
Also, there wasn't a location listed for the concert, so I assumed Princeton, NJ.
