Philadelphia Orchestra, Zoo in musical menagerie

On Saturday, the Philadelphia Orchestra and the Philadelphia Zoo will offer a musical menagerie extravaganza - the Carnival of the Animals concert and the Zoo on Wheels.

The orchestra will perform at 11:30 a.m. in Verizon Hall, creating some of kids' favorite sounds of beasts and creatures galloping, hopping, and flying through the air. Works from composers Benjamin Britten and Edouard Lalo and an excerpt from Saint-Saens' Carnival of the Animals will be featured.

The event begins at 10 a.m. with the Philadelphia Zoo's Pre-Concert Adventure in the Perelman Theater, where visitors can interact with animals featured in the concert. From 9:30 to noon, the Zoo on Wheels will be outside the center with naturalists to teach about mammals, reptiles, and other creatures.

If You Give a Mouse a Cookie

this weekend through June 27.

Based on author Laura Joffe Numeroff's best-selling novel, the show tells the story of an innocent boy who generously offers a cookie to a demanding little mouse. His action triggers escalating requests that result in chaos. Adapted by Jody Davidson and directed by Whit MacLaughlin, the play is best enjoyed by ages 5 and older.

Relive the British Invasion on Sunday at Longwood Gardens as it presents "Ladies & Gentlemen, The Beatles," a fireworks and fountains show.

Beginning at 9:15 p.m., the spectacular will feature Beatles music, opening with "Lucy in the Sky with Diamonds," followed by "Penny Lane" and other classics, and a finale of "The Long and Winding Road." From 3 to 7, families can dine at the gardens' Summer Barbeque Feast, and visitors can bring chairs and start reserving spots for the show at 3 p.m.
