Nice cozy setting. I like that the show gets the audience to participate.
Personally, I don't think show is entirely appropriate for kids. There is an Austin Powers segment and he makes suggestive jokes. Parents may want to cover their kids' ears and maybe eyes, depending where you sit. My 11 y/o was shielding his eyes when he saw a female dancer bent over in her dress with white underwear with her bum facing him. Awkward moment!
Otherwise, music was very real and a nice assortment! Great to get kids exposed to music from the past instead of what is playing nowadays.
