I'm very lucky to be joined for this episode by renowned rock photographer Bob Gruen to discuss his thrilling and action packed memoir; 'Right Place, Right Time'.

Bob shares the fascinating story of his friendship with John and Yoko - from the early days on Bank Street to preparing a book to mark Yoko's 80th birthday.

Bob took some of the most recognizable pictures ever of John and Yoko and captured almost every key moment of their life in the US.
