Druids can Perform just fine, they just don't get much of a benefit from it. But how 'bout an Animal Speaker Bard with a pet from the Sylvan Sorcerer Bloodline?
Well first of all if you honestly want to be a dancing druid I suggest not investing so heavily in cha or str and take dervish dance and bump up dex. I'm saying this because it's a bigger deal to have higher ac, reflex, to hit, and damage then it is to have bonuses to social skills and carrying capacity. Then just invest a little more into social skills and you'll be set.
Remember to use your spells to your advantage when dealing with roleplaying and social encounters. They will help define your character.
