Pharrell Williams took a trip down memory lane with Jay Z, as they surprised fans and performed several of their old collaborations at the Coachella music festival on Saturday.

As the Happy singer was performing his debut solo single Frontin, Jay Z joined him on stage to spit his verse from the 2003 hit. The duo continued with arguably their most popular collaboration, Excuse Me Miss, which was released the same year, and its sequel La-La-La (Excuse Me Miss Again).

It was only right that they also performed their 2000 hit, I Just Wanna Love U (Give It 2 Me), and the crowd didn't miss a lyric when Jay Z asked them to sing along.

Yet, Jay Z wasn't the only big star that joined Pharrell on stage at his Coachella debut. During the first week, fans were also treated to Snoop Dogg, who performed Drop It Like It's Hot. No Doubt's Gwen Stefani showed up for Hollaback Girl, as did Nelly with Hot in Herre. Both songs were produced by The Neptunes, a musical duo comprised of Williams and Chad Hugo.

Busta Rhymes appeared during the second week for Pass The Courvoisier Pt II as well as Pusha T with Grindin and Usher, who performed his Pharrell-written hit U Don't Have To Call. Talk about star power.

"Thank you @coachella for giving me one of the best experiences of my life," Pharrell tweeted on Sunday, before he thanked everyone who performed with him.
