On M*A*S*H, what was the name of the song that Father Mulcahy came up with?

Could it be called the "Second Korean War Song", composed by Mulcahy?

I've found a sourec that cites the following lyrics:

"There's no one singing war songs now like people used to do;
No "Over There," no "Praise the Lord," no "Glory Hallelu";
Perhaps at last we've asked ourselves what we should have asked before;
With the pain and death this madness brings, what were we ever singing for?"

It can be heard in the episode "Dear Uncle Abdul" (1979)
