Does anybody know how the ending bit of Andy McKee's Rylynn is played? I mean, the part when he starts playing harmonics and taps at the same time. I've recently learned the song, but I usually play the electric guitar, so the tapping bit's got me confused!
Grrr!!! Rrrr!!! Rawr!!! Meow???
Watch the youtube video.

he uses his right index finger to "fret" the harmonic and his thumb to play the string, while his left hand plays the rest.
