Which group performed before more live audiences of 10,000 and of 50,000 and of 100,000 ... in both teh 50s? 60s? 70s? 80s? and 90s?
Cliff Barrows, George Beverly Shea, The Billy Graham Evangelistic team holds all the live performance records. The record in Africa, the record in Asia, the record in Europe, the record in Latin America, the record in the US.
The only thing that comes close in competition is the annual events in Mecca.
The secular world is 3rd class on personal appearances.
When Catholics and Protestants sing the same song world wide, as they do for Christmas and Easter, Those are the all time records. In May both Catholic and Protestant will sing HOW GREAT THOU ART on the same Sunday. That is the largest non-Holiday song of all time.
Quite an accomplishment for a song that began as a poem written by Carl Gustav Boberg after a thunderstorm in Mönsterås, Sweeden in 1885.
"How Great Thou Art" also popular among Methodists, but it wasn't added to the Methodist hymnal without a fight. Seems some big shots in the church were opposed to the hymn because of its popularity among the unwashed rabble who attended Billy Graham's crusades.
