Matt and Alice talk to Dan Richter, friend and live-in assistant to John Lennon and Yoko Ono in the 1970s. An American who, in his own words, "came along for the ride: a co-conspirator, confidant, assistant and dope-buddy", Dan gives them a behind-the-scenes glimpse of the private world of John and Yoko. He recalls the making of Lennon's legendary hit 'Imagine', and tells them whether he believes the couple were truly compatible.
