Song Help

[kaseyman]

I have been working on the Willie Nelson classic, "Blue Eyes Cryin' in the Rain." I have the chords downpat and am trying to add the "riffs" between the chord changes. I was able to figure out the first two runs in the first verse, haven't been able to figure out the one at the end of the verse, or the two in the chorus. Never learned to read music, just love strumming the chords, but want to add abit more to my playing. Any help will be greatly appreciated.
Thanks......
