In some cases it is possible to improve upon an artists original recording.On Anglo International the late Andrew Blakeny Edwards did a home recording that was obviously not for the general public to hear.It had a number of mistakes and I did not think it fair that it was issued like that,particularly as he was such a brilliant and precise player.With carefull editing (pinching a bit from where he does play correctly and inserting it into the mistake)it became an important addition to the collection.
