In 1955 the American evangelist Dr. Billy Graham began a tour of Scotland, the
All-Scotland Crusade. He drew a 90,000 crowd to the national stadium at Hampden,
and had a full house at Glasgow's Kelvin Hall every night for six weeks.
The crusade reached more than 2.5 million people and 50,000 Scots came forward
at the meetings to "make a stand for Christ".
