Boil 'em Cabbage Down (drop thumbing)

Been working hard on my drop thumbing technique, which is a tricky but great way of breaking the monotony of the 'bump ditty' frailing rhythm. It's hard to get the thumb to drop down and pluck an eighth note before the fifth string pluck, but its getting automatic now and gives a useful variation to throw into a tune.

Here's my version of Boil 'em Cabbage Down using drop thumbing.
