Gary, I was not going to post this until I was ready to type in one of the other variations, but since you are getting ready to do this, you should know that I made an error in the transcript above. I left out the last part of the chorus which was on the next page. Sorry. The full chorus goes like this:

Chorus
Who'll sing for me (Who'll sing for me)
when I am gone, (when I am gone,)
As I so oft (As I so oft)
for friends have done? (for friends have done?)
It won't be long (It won't be long)
till home I see, (till home I see,)
When I am gone (When I am gone)
who'll sing for me? (who'll sing for me?)

There seems to be some part switching in the repeat segments. I will leave you to do that however you like. I couldn't figure out how to make it more clear, so I just kept the same pattern throughout.
