Andy Williams and St Marks Church

Eric Mullen: I seem to remember Andy Williams visiting St Marks Church around about 1980 - I don't know why he would have done this but maybe I am getting senile and it didn't happen. Can anyone confirm? 

Regarding Eric Mullen's query about Andy Williams visit to St Mark's Church I can confirm that he is indeed right and that his memory hasn't let him down! 

After doing some detective work liaising with Mark Duffy, he told me that his dad, Jim Duffy, Colinton, Edinburgh confirmed that St Mark's School sang with Andy Williams at St Mark's Church in 1981. This was beamed onto the Johnny Cash Christmas in Scotland Show.
