I was looking at the Walk Arounds in the Ryan's Mammoth tunebook today. There's one in particular that I like: "Brudder Bones". It has a very bluesy feel. It's kind of like the missing link between "Crabs in the Skillet" and "Minnie the Moocher".

Anyway, as with all the Walk Arounds given in this book, it's in 2/4 time, but has a second section - the "Dance" part - which seems impossibly quick. It doesn't specify a change in time signature, but it feels like this section ought to be in 4/4. It's the same with all the other Walkarounds listed in Ryan's.

Or maybe I'm just misreading it: I don't do much music-manuscript reading these days, and never was much good at it anyway.

You can have a look here:

And I managed to find someone playing it on YouTube too:

He plays the second part at the speed I would expect, as if the time signature were now 4/4.

Can anyone enlighten me? Thanks
