For those who have seen "Iron Jawed Angels", isn't the version the women sang in prison of "Will/may/Can/Whatever the Circle Be Unbroken" incorrect for that time period? In the credits,the version sung is attributed to AP Carter.... The movie was set during the WWI era. The lyrics they sing are nothing like Fanny Crosby's or Ada Habershon circa 1907/08...can anyone enlighten me? my email address is ginacook34@hotmail.com thank you!
