I bet you guys have really planted a seed with the Jungle book.. definitely one of my Disney Favorites and Definitely something I could see Casey and his combo marching around the room with ...
... He could get a Audience Congo line going (not sure the fire department would love that in all venues.. but some venues a conga line would be awesome)
As for Jacob.. yes, seeing Casy Jacob and Taylor perform live in Oakland in december I was impressed with all of their spirit. Jacob did seem to have particular connection to the crowd and glow to him even if I don't recall him saying more than a few words up on stage.
He's got what they call a "stage presence" I think.. something hard to define and not the same thing necessarily as being glib or articulate (and he might be both of those too).. it's more about just a comfort and command of the stage and an uncanny way of making people comfortable looking at them.
I liked this thread on it:

Quote:Be very energized on the inside, but hold that energy just beneath your skin, with stillness and confidence. Have 110% energy, allow no more than 10% to leave your body.
This is also something known in Western mime, and mime Lindsey Kemp passed something of the kind on to no less than David Bowie. Also this: keep a sense of stillness in your spine.
I know this requires a lot of imagination and visualization, and it is easier to explain and teach in person than it is to describe. But I have absolutely seen it work.
