This is How I'm Made is interesting. I saw it only aired in one episode, I wonder what is wrong with it. I can't really decide if it's really great or just ordinary. With so many segments it could probably be hard to air everything every season, but until season 29 it would have been possible to air every Sesame Street News segment once a season without repeating (and without showing two an episode), and there doesn't seem to be anything objectionable in this. After looking up some info on the wiki and seeing that Joe Raposo wrote the song I quickly realized this came after his death (I wonder if Raposo has any other posthumous songs in season 20).
It is weird that they just had Martin Robinson do the announcer voice. I saw a comment that said Jerry Nelson was likely busy but if that's the case they could have just reused the same opening from most of the others (it would be interesting to track how many Sesame Street News segments have unique announcements at the beginning instead of the usual... and this one basically has Robinson reading Nelson's usual line). I wonder if this was intended to be a news segment, for the most part you could remove Kermit and it wouldn't make a big difference. And maybe it's just me but Kermit looks superimposed into that segment. Between this and next season's "Bird Family Song" it seems they were starting to have news segments that were primarily song segments.
With the exception of a few Dr. Nobel Price segments and the complete rainy day segment with Telly and Mona, I guess I've now seen all the news segments in their original English audio.
I just watched that Don Music segment, that is a good one. Although the back-up singers are all male, it sounds like there's a female vocalist or two in that. I don't think any of the kids were singing along.
I had trouble determining who performed the singer in that Danger segment, at first it sounds a bit like Jerry Nelson but at times it doesn't. I'm guessing Michael Earl or Bob Payne, they seem to have done Jerry Nelson-like voices. I should look up the song on the wiki and see if it says. EDIT: Okay, I see on the wiki that it was Jerry Nelson as the singer.
