There's this church group called EFY that I listened to a lot. One of their songs is called 'We Believe.' One verse of it, in the chorus, is 'We believe in obedience ringing the bell of the free..." For several years, I thought it was 'We believe in the beady ants ringing the bell of the free', and I sang it like that every time. Finally one day I had a breakthrough.
