I meant to post this months ago but here finally are two performances from the Camp Hollywood Jitterbug Championships back in August. I wasn't at Camp Hollywood but I did get to see both groups do practice performances a few weeks ahead of time.
This is the first place performance,
the One2Swing Jitterbugs. The music in the first half is "All the Cats Join In" and the choreography pays homage to the Disney cartoon.
This is the second place performance,
the One2Swing California Rolls. Each group has the same choreographers (Ben and Sheri Yau, thus the One2Swing in each name) and I think the choreography for this one is amazing. It's original and fits the music so well.
