Reddit reviews All We Are Saying: The Last Major Interview with John Lennon and Yoko Ono

This was the Playboy interview, and it was recorded in the 1980s. Specifically, it was recorded over several days in September 1980 at John's home in New York City. The whole interview supposedly lasted somewhere over 10 hours. Unfortunately, the entire thing has never been released.

That said, most (but not quite all) of the segment of the interview where they discuss the Beatles' songs has been released/broadcast on various sources, and all of the available bits of the interview have been collected on a bootleg, so if that's what you're interested in, you should be able to track it down. The bootleg is about 3 hours long. Go post a request for it on the Bootlegzone board and hopefully someone over there will share it.

An edited transcript of the full interview is also available, published two different times as a book. The first was in 1981 as The Playboy Interviews with John and Yoko, and the second time was around 2000 as All We Are Saying. The credited author of both books is David Sheff (the reporter who conducted the interview).

The Rolling Stone interview is also very interesting, and John does talk about a handful of songs in that interview as well, along with all sorts of other Beatle topics. He wasn't in a great mood that day, so a lot of it is really negative, which is too bad because it's probably the most thorough interview John ever gave discussing his Beatle years.

And that's also unfortunate because just a few days later, John gave another interview to a New York radio deejay named Howard Smith, and John is in a much better mood, and covers many of the same topics with John being much more upbeat. The only downside is that interview is much, much less thorough than the Rolling Stone interview, which is why the Rolling Stone interview ends up being used so heavily in most Lennon/Beatles docs.

Anyway, you can buy the whole Rolling Stone interview off of iTunes as an official release. The Howard Smith interviews are also available on an out of print release, though if you look around the internet, you might be able to find that one as well.

Good luck!

It is the entire interview, not the edited one that was published in Playboy in 1981. A very good read!
