The tune is very similar to, oh, I'd estimate-- a couple of hundred other gospel songs. In fact whenever Hardi suggests a song theme, jokingly, this is pretty much the tune that comes along with whatever lyric I improvise. Bluegrass gospel often is set to this type of tune.

"Sankey", yes.

One example of a tune that will sound much the same as this one is "Uncloudy Day." Some of the pitches in the YouTube video are the pitches often used in a harmony line just above the melody, which are often added in as variations in a gospel song.

It's pretty though. :~)
