Banjer,

I Don't know the specifics on these two songs, but I do know that as a general thing, the Salvation Army and other evangelical/missionary organizations wrote religious lyrics to popular melodies of the time(late 19th Century)--it was a wonderfully effective way of spreading the message, because an enthusiastic crowd couldjoin in on a hymn instantly--of course the side effect has been that today, most of us think we are listening to religious music when we hear music from 19th century beer halls--
