In case you missed it I’m referring to Bobby Bonsey (white shirt, red tie) and his move on Jana Grulichova (red shirt and black vest). If you did miss it then go back and watch it again. I’ll still be here when you're done.
I don’t know about anyone else out there, but I’m going to say up that I think that Bobby’s move on Jana was inappropriate.
I’m not sure what they’re relationship to each other is (dance partners, friends, whatever) But even if they know each other, or if it’s pre-planned, I still don’t think it’s something that should happen in a dance competition.
Aside from being kinda creepy, there’s still the matter of the use of direct contact and partnered lead and follow in a solo contest.
It’s one thing to play off of one another through visual cues or mini-challenges (E.g. I do a move, then you do it better), but by consenting to following something physically led on you, you’re basically submitting to another dancer. That's exactly the opposite impression you want to make in a competition.
Check out the 2008 Camp Jitterbug Solo Charleston contest towards the end of the dance off (which starts at 3:50) between Sharon Davis and Carl Nelson.
