[ARSCLIST] Royal Coronation and more



Hi all -

You may also find some interesting audio at www.soundarchives.co.nz and by
searching Royal Family, or other keywords you will find that Queen Elizabeth
made recordings from Auckland, New Zealand, in 1953. There are other recordings
available there also.
