1962
Harry Williamson (treble 1959-1963)
From Harry: "A posed photograph outside the South Entrance near where the choristers robed. This was when the collars were changed from the original starched Edwardian style to the softer modern 'bib' which was a lot more comfortable." [The bibs continued in use until the early 2000's, when they were replaced by ruffs. The cost of cleaning the collars had become prohibitive.]
