Right, as stated it was a concept show. Will Rogers had been a star in various Ziegfeld Follies--so they attempted to tell his life in the format of a Ziegfeld Follies show, with all the standard acts (ie there's a dog act, various production numbers, etc).
I'm extremely mixed on the show. I think the actual material is often mediocre--it's not Coleman (or Comden/Green's) best work, and Peter Stone's libretto is pretty pat, although there are a few good songs. The reason it works is because of Tommy Tune's spectacular staging--I rarely, if ever, play the cast album, but the original Broadway production was filmed for Japanese TV and it's often thrilling to watch, even on video. I assume most productions largely are based on Tune's--but I wouldn't really have any interest in seeing the show otherwise. The original cast, led by Keith Carradine, Dee Hoty and Cady Huffman was also very appealing.
Here's Our Favorite Son from the Japanese broadcast (so with subtitles...)

If anything my problem is I personally find it a bit exhausting to watch all of--the music often starts to kinda blend together, etc, though it does have some touching moments.
