[RR] Can ANYONE name this tune?

[Commander Pier]

Here's a memory test for the old timers.  I recall hearing the following chorus in church as a preteen/teenager (5th to 8th grade) in the early 70's.   It goes like this:   It won't be long now, its gonna be soon my friend, I hear the call upon my heart.   The question is, is that from a real song, and if so, what are the rest of the lyrics?   Kelvin
