Tony,

The fake book I learned it from had it in F so that's where I learned it. In my guitar/beatbox days I would end the song..........
"help me make it through the night"........"and don't look so sad. I know it's over."

which was the lead in for Kristoferson's "For The Good Times" also in F. Those two songs segue very nicely.

God Bless,
Don
