eeeeeh crowd surfing? that's dangerous. that part I'd be like you about. I know that tour is OK, the music is fine. (I don't like it - but it's not promoting anything bad) But I'd be too chicken to go crowd surfing.
However, the tattoos, no biggie! they're Henna Tattoos. I have 2 as well. they only last about a month...mine are on my ankles.
