Here are some highlights: Midsummer Night Swing is an outdoor dance party where anyone can dance the night away to live music. This Saturday morning children can learn the basics of ballroom, tango, merengue, and swing dancing at Midsummer Night Swing's Kids Day ( a second kids day will be held on July 14th). This summer, Lincoln Center Out of Doors celebrates the spirit of the Sixties with over 100 free performances taking place on the plazas of Lincoln Center. There will be dance-ins, poetry, puppets, music, magical juggling, Chinese Theater, African Ballet, Hawaiian Dance and more. Many of the performances are geared for children. The festival opens with Arlo Guthrie and Roy Brown on August 2 followed by too many great events to list. Here are some stand-outs, but definitely check out the entire list of events: Enjoy a day of family fun at the Lincoln Center PlayDay Dance In. Kids will learn the Apache line dance and the hustle, recycle everyday objects into musical instruments with Bash the Trash, and check out retro styles at the Hippie Flash Sideshow Fashion event. Mark Nizer Combines comedy, movement, music and technology, juggling genius as he amazes his audiences juggling just about everything including the kitchen sink. The Bread and Puppet Theater has been enacting its radical Utopian vision in larger than life puppets for over 40 years. You don't have to agree with or even understand the politics behind the performance to be amazed by the pageantry.
