This weekend in Lawrence: twists and turns galore in Kansas Repertory Theatre’s “Angel Street,” a party in the park hosted by Headquarters, the “Simple Gift” of (free) music and a Pokemon-minded history lesson at Oak Hill Cemetery.

Headquarters Presents “Everybody Day!”

11 a.m. to 6 p.m. Saturday, Watson Park, 727 Kentucky St.

Lawrence’s Headquarters Counseling Center is hosting a community celebration in support of suicide-prevention awareness Saturday, and everybody, as the event’s name implies, is invited.

Live music, kid-friendly games, yoga in the park, free food, a rummage and bake sale, and “much more” are all on the roster, with proceeds benefiting Headquarters.

Simple Gifts: A free community and university music celebration

7:30 p.m. Saturday, Lied Center, 1600 Stewart Drive

Take a break from the heat and enjoy the healing power of (totally free) music at the Lied Center, where the Kansas Sinfonietta, Lawrence Children’s Choir, soprano Vanessa Thomas and pianist Chaeyoung Park are all slated to perform Saturday.

The concert is made possible by the Lawrence Children’s Choir, the Lied Center, the Kansas University School of Music, the Spencer Museum of Art and the Lawrence Arts Center. Admission is free, but tickets are required and can be picked up at the Lied Center ticket office between noon and 5:30 p.m. Friday. Call 864-2787 for more information.

Poke(mon) Around Historic Oak Hill

1 to 3 p.m. Sunday, Oak Hill Cemetery, 1605 Oak Hill Avenue

Sunday sees the second installment of Watkins Museum of History’s two-part family-friendly program dedicated to “Pokestops,” as they’re called in the mega-popular Pokemon Go game, around Lawrence’s storied Oak Hill Cemetery.

Throughout the afternoon, museum interpreters will offer historical insight (the cemetery was originally designed as a public space and memorial to the victims of Quantrill’s Raid more than 150 years ago) into why the Oak Hill “Pokestops” were chosen, ideally offering a “richer experience of historic landmarks and (to) ensure respectful interactions with the sites.”

For more information, call the Watkins Museum at 841-4109. Now, go out there and catch ’em all.
