This is a perfect example of tasteful waltz playing in the lower register of the banjo. Scruggs uses hammer-ons, slides, and pull-offs to create a fun, yet difficult arrangement of All the Good Times are Past and Gone.
Playing melodic style in a waltz can be tricky so play along with the All the Good Times are Past and Gone backing track a ton to get this one feeling comfortable. Luckily it's not incredibly fast!
A basic backup version that demonstrates moving from vamping in 3/4 to playing tasteful rolling backup in the style of Earl Scruggs.
