great song and great solo.

You should be able to pick out all the notes in the solo via D major pentatonic scale. Start in the 7th fret position.

The last higher notes at the end of the solo target D major chord tones above the 12th fret:
15th fret b string
14th fret g string
17th fret e string

Hope this helps, have fun!

oh yeah, this video gives some of it away:
