The dance at the end of Dance My Life 1 is awesome! Or there are a lot of group dances in Song and Dance Youth
You can go watch High school musical (Song and Dance Youth) in there too.
Despacito's group dance is very simple.
There's also a very old song called "Lost Love Front Alliance", which is a very good dance.
Recently, Panama is a little bit more recent, the dance is also relatively simple, jump up and look good. jumpstyle dance, very suitable for group building dance!
