Here’s the full description of the talk via the Hay Festival website:

This special event marks the UK launch of Kent Nerburn’s award-winning work of creative non-fiction depicting the epic and intensely moving journey he made over 20 years ago with a Native American elder named Dan. Musician Robert Plant picked up a copy of Neither Wolf Nor Dog whilst touring the States in 2014 and his passion for this masterpiece has led to its publication here in Britain.

The talk was filmed, and it’s available to stream or download for £2 from the Hay Festival’s website.

One fan took a photo with Plant after he talked on stage.

This isn’t the first time that Rankin has been photographed with a member of Led Zeppelin. He also posed for a photograph with Jimmy Page during a literary event in Belfast in September 2016.
