I wonder if somebody in this forum would be able to help me with my request. I have tried searching high and low for the master files of the Janet Mayo announcements, I have tried more than one company and it would seem even LUL don't have or don't know where the files are if at all.
Is there anyone in this forum that has, or knows anyone that recorded them years ago?
Also this is probably even more unlikely, but does anyone have a recording of the original male voice test message Central line test 1 2 3 4 5? That was unfortunately lost when the trains went over to Connect.
And the files at that link are hardly master file quality as requested by OP, they seem to have been recorded in a noisy train. Is it the scripts that are wanted, or the specific voice? I don't have either by the way.
