If you have just downloaded the interviews from for the love of then you will have noticed the Mucho Mungo demo recorded by John Lennon. Here I've included two recordings by Harry and John. Both recordings are from the same take. As both recordings are mono but one features the vocals far more clearly whilst the second has much louder instruments it may well be that they are the left and right channel of the stereo tape.
The first recording of Mucho Mucho finishes after the song whilst the second recording continues for another minute with a run-through of Harry singing Mucho Mungo/Mt Elga. Whilst the quality is not brilliant, it is passable and so far the only session recording with Harry and John.
