Mary in Ky., this is probably not the Porgy and Bess "I'm on my way." The one I'm referring to is an old negro spiritual:

"I'm on my way, to Freedom land
I'm on my way, to Freedom Land
I'm on my way to Freedom land
I'm on my way, Great God, I'm on my way."

Then you can add verses about anybody (Your brother, Sister, Mother, Dad, Boss, etc.), like this:

I'll ask my brother to go with me (3 times)
I'm on my way, great God, I'm on my way

Or:

I'll ask my boss to come with me (3 times),
etc.
If he says no, I'll go anyhow (3 times),
etc.

If you won't go, let your children go (3 times).
etc.

If you won't go, let your mother go
etc.

You can do so much with this and everyone sings! A lot of fun and you can find some good harmony. Regards, Jim
