I remember this one really well. I was already assigned a part on the Service Meeting when the PO and Sec. "remembered" that a talk had to be given for the program. I ended up giving one part coming down for the next part and then going back up for the Pioneers Assist Others talk.
Both the Pioneer and publisher had the option of rejecting the pairing. I see comments where some felt forced to work together. The program was a flop. The CO would come and ask about it and I had to beg people just to sign up.
