Songs you could use this for:
Edelweiss (Rodgers & Hammerstein) - from the Sound of Music
Good Night Irene (Leadbelly) - he's doing pluck-strum-strum, but on uke, this strum complements it
Norwegian Wood (Beatles) - written in 12/8 but this strum suits if you leave off the last up: d - dud - As there are no live clips of the Beatles playing the song on YouTube, this animated quasi marionette clip is at least interesting!
Waltz #2 (Elliot Smith)
