Written by Fanny Crosby in 1891, performed here by the Table Singers, My Saviour First of All has a traditional story attached to it.
There was a man in London proclaiming himself to be the returned Jesus Christ, and he was attracting a crowd of followers in the street. But then a Salvation Army band happened to pass by, playing this hymn. And someone in the crowd who knew the words cried out, “Let’s see his hands! Like the song says, ‘I shall know him by the prints of the nails in his hand!”
No nail-prints being visible, the followers went home.
