I saw almost all of the Ms. Johnstones.
I felt like Petula Clark nailed both the acting and singing.
Carole King was surprisingly good acting but sounded like she had some vocal difficulties.
And Helen Reddy sang the material well, but her acting was bad.
Mind you, I was super young when I saw this but I absolutely loved the show and saw it a lot-as teenagers tend to do with a show :)
