I'm not a fan of Katy Perry but she has always done well with charities, whether it is time or money. Gotta respect her being there to do the song when she could have been doing just about anything else.
Nice! Nice to see Katy dressed normal. Never been a fan of hers but she does great charity work. Wish other performers would follow her lead. Also don't care for John Stewart, but in this instance he gets props.
