Loop John Beatle

40 years ago today:

On April 7, 1966 in an afternoon session at EMI's Studio 3, THE BEATLES, with GEORGE MARTIN producing and GEOFF EMERICK engineering, used manually controlled tape loops to add effects to "Mark I", the JOHN LENNON song they had begun recording the day before at the first session for what would become their "Revolver" LP. The song would be renamed "Tomorrow Never Knows".

These are all very small files of each of the five loops used on the finished recording:
