We’re not entirely sure the origins of the song, but we learned “Big Ball In Brooklyn” from a live Flatt & Scruggs record.
The instrumental part at the end is called “Fiddle Fingers”, which happens to also appear on the same live recording. That wasn’t by design. Rebecca suggested it as an appropriate tag for “Big Ball” even though at the time I’m sure she hadn’t heard the Flatt & Scruggs performance. A happy accident, I guess!
In any event, we can at least take credit for combining the two. Although it’s not really much of a mash up, it’s just kind of one song, then the other.
