Engineer at Abbey Road Studios. He worked on Kate's albums Never For Ever and The Dreaming, as well as the single December Will Be Magic Again.
In 1981, he found he had cancer, and while receiving treatment he occupied himself with the task of going through the vaults of the studio and seeing exactly was and was not there with regards to the Beatles' many recording sessions. He created a 'catalogue' of sorts, and while finding out exact dates for recording sessions also dubbed rare takes and demos.
John Barrett passed away in February 1984. He is mentioned by his nickname Teddy in Kate's song Moments of Pleasure.
