Today comedian Kenny Everett’s came out to John Lennon’s house, Kenwood, to tape an interview for his BBC1 radio show. I couldn’t find a recording of this, one of many Lennon appearances on the show, but The Beatles Bible describes it thusly:

In the recording, Lennon appears either tired or under the influence of drugs. He attempts to explain the lyrics to “Strawberry Fields Forever,” but has trouble remembering the song. He does, however, admit that the song took so long to complete that he lost perspective on its meaning, but was gradually realising that it reflected his confused state of mind at the time.
