We’ll officially welcome spring this weekend, and while the temperature may be see-sawing, there are lots of events to put an extra spring in your step at the end of a long week. Here are just a few.

‘Dirty Dancing’ in concert

Have the time of your life at this nostalgic musical performance on Friday night. This is a great show for those who have never seen the classic 1987 film “Dirty Dancing” and those who have seen it a dozen times.

During the show, the audi­ence will watch the digitally remastered film while live singers and musicians perform the music along the way. This movie’s smash-hit original soundtrack is perfect for a concert that allows the audience to sing along, dance along and connect with this timeless story.

Even after the credits have rolled, more music awaits for those in the theater. The show will be held at 7:30 p.m. Friday at The Palace Theatre, 21 W. Otterman St., Greensburg. To learn more and get tickets, visit westmorelandcultural trust.org.

Genealogy workshop

Tracing family histories is an increasingly popular hobby, but if you want to self-­publish the results of your painstaking research, it can be intimidating to get started. This weekend, the Westmoreland County Historical Society will show you the ropes.

Westmoreland County’s own Richard Barnard will present the process he used to make keepsake books of his family history. He’ll talk about how to research, organize and create your own publications and presentations of family trees.

The workshop will take place from 1 to 3 p.m. Saturday at 809 Forbes Trail Road, Hempfield. The event is free for Westmoreland County Historical Society members and $5 for nonmembers. To RSVP, visit westmoreland history.org.

First Day of Spring Hike

It could be chilly, it could be breezy, it could be a glorious day or pouring down rain. But the first day of spring always carries one promise: The renewal of nature is on its way, from the return of birds and animals to the budding of trees and flowers.

See the ways that nature is changing on this first-day-of-spring hike at McGinnis Nature Reserve in Murrysville, organized by Westmoreland Conservancy. The hike will head up the Blue Trail and examine the signs of nature waking up along the way.

The hike will start at 4 p.m. Friday in the parking lot of the reserve on Hunter Drive. Register at westmoreland conservancy.org.

Green Day tribute

Punk fans are in for a treat at the Lamp Theatre in Irwin this weekend. Letterbomb, a Green Day tribute band, will blow the doors off the theater with their authentic performance of the alt rock band’s high-octane hits.

From “Basket Case” to “Good Riddance” to “American Idiot,” Green Day has been creating memorable songs and selling out arenas for more than three decades. Letterbomb will deliver a high-energy show that authentically mimics the sound and style of the band with great musicians and all the hits you love.

The show will be held at 8 p.m. Saturday at the theater, 222 Main St. Tickets are $30 apiece. To learn more, visit lamptheatre.org.
