Subject to each individual venue's rules, an Alive! '75 show is open to all ages. As far as Alive! '75 is concerned, children are more than welcome when accompanied by a responsible adult. We absolutely LOVE when we see multi-generational family members at our shows.
Be aware that some shows are explicitly 18 or 21 and over based upon the venue. Also, please bear in mind that the show may include references to drug and alcohol use, so you are advised to use your discretion. It's always great seeing adult fans on hand with their little ones – the choice is yours.
