His show is mostly kid oriented and people literally are throwing their kids on the stage to participate.
During my 20 years as a DJ, the one thing I learned that made me popular was this. At many intimate, family-type parties, don't worry about entertaining the adults so much as entertaining the kids. Parents love to watch and film their children playing games (especially winning the game), dressed in costumes and hats, making faces, interacting with the other kids, etc. We all know parents are obsessed with two things.....themselves and their children! Please the kids and you please the parents.....sometimes without line dances even.
(But.....WARNING: do NOT do this at weddings and "giant" affairs!)
I worked with kids for a few years. Some of the ideas I used:
Jr. Miss America contest (play "A Pretty Girl is Like A Melody)
Mr. Muscle Man Contest (they do muscle poses...play Macho Man)
Balloon race (hold the balloon between two people...using the body only...no hands....play William Tell Overture)
Dance competition (teach them basic moves in standard dances...tango, cha-cha, waltz....dancing with their parents)
Freeze Dance combined with Huggy Bear and Coke/Pepsi
Talent show with kids providing the talent
Father/Daughter dance (play Daddy's Little Girl...even as corny as it is today)
Mother/Son dance (I let them dance to Disco and make up the moves)
You can stretch many ideas out to fill out a 3-4 hour gig with enough patter in between.
But the point again....whenever possible, for "family" events (birthday parties, etc) you don't need to focus on the music....only the kids.
