My old high school does this Follies show every year, with the drama teacher writing the script. Well, the one time I did it, she decided on a tribute to Broadway.
The script was basically a rip-off of The Producers and A Funny Thing..., and she added in stuff like "I Enjoy Being a Girl" and "De-lovely." Top it off, she added in this whole subplot involving a theater owner and her brother, using Copacabana.
The main leads were good, but...the woman cast her daughter in the role of the theater owner Millie. The girl can't act. She played that and her role as Ms. Molloy (we did Hello Dolly that year as well) exactly the same way.
Ow. My head hurts from thinking about it
