Lacey,

Sorry, I haven't been able to locate 'Best of Me' anywhere on the web. There are quite a few sites with Delbert Mcclinton songs, see Google search for 'guitar chords delbert mcclinton'

http://www.google.com/search?q=guitar+chords+%27delbert+mclinton%22+&start=0&ie=utf-8&oe=utf-8&client=firefox-a&rls=org.mozilla:en-US:official

( if this doesn't display in full as a link, just cut&paste the whole thing into your address bar )

You might have some success if you contact the webmasters on these sites, or they may add the song later themselves.

Best of luck!
PJ
