OK, here's a bit of a puzzler. I had this John Lennon interview identified as an RKO Radio broadcast from September 25th, 1974.
It circulates in two versions: here is the unedited recording, complete with questions, from a rebroadcast in 2005 (on Black Cat's CD Oh Yeh?). There is also a much shorter and lower-quality version, with questions removed and music included, presumably from the original airing.
Internal clues date the interview to the first few days of August 1974. So far so good, right?
Well, there is another interview out there claiming to be a September 25, 1974 RKO broadcast. It does indeed contain a couple of snippets from the above (which I have removed). But the bulk of it seems to be from a completely different date (or dates), possibly 1975, based on the reference to Allan Williams' book. Several pieces of it will be familiar to viewers of the Beatles Anthology documentary.
Can anyone clear up just what was recorded and/or broadcast when and where? We may have to wait for Lennonology to solve this mystery.
