Further to the chords question:
It looks like you can buy for $3.95 sheet music of a "You are my Sunshine" arrangement by DUANE EDDY!
from www.laurasmidi.com/cgi-bin/shmtitles.cgi?newtitle=You%20Are%20My%20Sunshine.

Also I found a midi file of an old-timer-pianee arrrangement of "You are my Sunshine" named pmn0041591.mid. But I can't remember where I found it.

You can print out the score of mid files using a free test version of "midi notate" from .
