Aaron, answers to your questions:
Cullen's Pyramid was syndicated. So yes, while it was taped at ABC along with its daytime counterpart, it was sold to individual stations regardless of their network affiliation. That's why your NBC station carried Bill while you saw Dick on Pyramid's home network, ABC. Kinda like the way H2 taped at CBS but was on other stations with and without network ties.
Speaking of Dick, he might've been in a rush to catch the first plane back to LA to do Bandstand - or his radio shows, or run his production company. Busy guy then.
