"I'm always trying to learn more about Freddie Mercury. A good source is this gentleman: Peter Freestone.
He was Freddie's personal assistant (starting in November 1979) and has some fantastic information on this conversation. Everything went great and this was one of my all-time favorite voice chats! This is very long (almost three hours), so make sure you've got your popcorn and drink!
Note: The information about Freddie's voice is something else!"
