Having started to listen to the Audiobook, which is fantastic and extremely well narrated, the narrators are

Chris Smith - Foreword
Mike Grady - Introduction and Comments/Footnotes
Samuel West - J.R.R. Tolkien

I started about 10am when I remembered I’d got it through Audible 😆. I have to say how good Samual West sounds reading as Tolkien. Recommended.

Agreed. It is an excellent reading. A lot of effort has clearly gone into his reading.
