While searching for John Denver’s Thank God I’m a Country Boy in the youtube, I found this one very interesting. Two of the singer did forget their line, but luckily they manage to recover. I think they are to be ‘professional choir singer’ student, which is why they know how to handle the situation. But I’m sure the first guy who forgot his line is very thankful that the next singer after him also forgot his line… Yea, Thank God!
