Gave it a reread, and have to agree.

Looks MUCH better now.

Overall the only points I am somewhat unsure about are the following:

Charming Performance: Its just....it should be a more social ability than Charm Person, not a LESS social one. After all, you sing/Dance/Rap/Whatever for it instead of just firing off a spell.
I would increase the duration, but (if thats considered too strong) add in a few actions that, if executed by the performer, immedeately end the effect?
Would make it more of a way to prepare social encounters/sing for peace than Charm person (which,m they also get anyway).

The Call Lightning Variant: Granted, it is worse than done by a Druid. Still, a Bard is NOT a Blaster CLass, so does he need it at level 1?
