Info needed about "Warped Tour" punk rock festival?

Daughter, 17, was invited to attend [for free, but I don't care] the Warped Tour; the 13th or 14th edition of a punk rock all-day festival. We are Catholics and do not like foul language, premarital , etc. Basic Fox News conservative family. Although some of the bands have mainstream songs even I have heard of and like, I am afraid that this environment will have immodestly dressed, punk rock teens who will be listening to profane lyrics and who knows what antics. Can't find parents whose kids did or did not attend this tour in other cities other years, and NEED DATA ASAP. www.warpedtour.com has no info except for sponsors, and I see Trojan condoms is a sponsor. Joy. Help!
