The third verse of Maggie Campbell is:

A-a-a, see see rider see what you done done see what you done done
M-m-m, see see rider see what you done done,
You done made me love you, now you' tryin to put me down

Maggie Campbell is a great song and features Charlie McCoy on the second guitar. Charlie was a mandolin player and frequently used mandolin tremolo picking on guitar.

I posted some lyrics to "Canned Heat Blues" a few days ago but I believe the ones you posted are perhaps more accurate than mine. You've done a fine job.
