Harry Potter and the Philosopher’s Stone, which was released as Harry Potter and the Sorcerer’s Stone in the US, is now free to stream on Audible. It’s the version narrated by Stephen Fry, and part of a series of initiatives launched by JK Rowling and friends to keep everyone entertained while they’re cooped up at home.

I remember buying the Fry audiobook on CD as it was unabridged and would last long enough to keep Rayburn amused on a trip driving to West Wales (a mission in which it succeeded) to see Vince and Michele.
The CD version came out in 1999. I am pretty sure neither Ben nor Isaac were born at the time of the trip, and they came into the world in 2000, so it could be coming up for 21 years ago.
