From my experience with telethons (not just MDA) the national organization discourages entertainment on local segments, as that is provided by the national program.
I’ve been to a few regional and national meetings for those involved with local telethon production, and the message was that the national broadcast hooks viewers with entertainment and some feature stories while the local broadcasts push for the money while highlighting the work of local organizations and those that receive their services. Running local entertainment would take away time needed to encourage the viewers to make the phones ring with donations.
Local broadcast inserts also have to prominently feature local businesses that donate to the cause. Entertainment would get in the way of that.
In Reno the two years I did it (1979 and 1980), that was the policy.
The businesses could be wide-ranging. The first year I did it, the producers forgot to tell me how far-ranging until two young women showed up from Joe Conforte's Mustang Ranch Brothel with a check to present on-air. Apparently it had been going on a while.
I was 23 years old and knew Mom was 200 miles away in Bishop watching on the cable, so I took the check, thanked them and then looked into the camera and said---"Mom---just to be clear, they're giving
me money---and it's for Jerry's kids."
The closest to entertainment we got in the Reno segment was in the second year when I was just about to go on air, felt a tap on my shoulder from behind, looked and it was Tony Orlando. He'd finished his two shows at Harrah's and still had some energy to burn. I asked the crew to get him a mic and we went on. He did every local cut-in that hour (I think 1:00-2:00 a.m.) with me and was terrific.
I have him to thank for my TV career. In between our first cut-in and our second, he asked what I did for a living. I told him I was a local radio disc jockey and he said "You're wasting yourself. The camera loves you. Get a job on TV."
It was something I'd thought about, but that was some pretty serious motivation and kinda kicked any doubts and insecurity to the curb.
A year later, I started as the weekend anchor at a competing Reno TV station, after having moved from programming and talent to news at KOLO-AM.
