Here's the live show that Kiedis described in Scar Tissue where John plays 'Under the Bridge' differently and causes Kiedis to sing off key.

Apparently John did this because Kiedis accidentally kicked him during the first song they performed, Stone Cold Bush.

The best part is when John screams the backing vocals for Under The Bridge.

I love the both of them
