None.

None. Some slapstick, comic violence between the band's sets, mostly from Bam Margera. However this is handled in an overly comedic fashion and is not meant to be taken seriously.

Nothing outside of the occasional song lyric/theme.

Many of the participants do these things, but it is strictly at the social level. No one gets drunk or high.

None. Some women appear in cages during the ZZ Top set, but they are clearly dancing and having a good time of it.
