WATCH: Rory McIlroy crashes Zurich Classic concert, sings karaoke after win

Picture this: You and your bud just won a golf tournament together and you celebrate by doing some karaoke.

Now realize that the tournament wasn’t your club’s member-guest and you and your bud are Rory McIlroy and Shane Lowry.

Yeah, this is something you have to see to believe.

After McIlroy and Lowry closed out the team event in a playoff earlier in the evening, they headed to the tournament’s postround concert at TPC Louisiana where a cover band out of England called “The Molly Ringwalds” was performing.

The band’s website says the performers “dazzle and engage their audiences with energy and passion, while taking them on a musical journey filled with all the hits that transcended the 80s and defined a generation.” They probably had no idea a now-25-time PGA Tour winner was going to help them take the audience on that musical journey.

Numerous videos started making rounds on social media Sunday evening of McIlroy and Lowry getting up on stage the band’s frontman telling the crowd McIlroy would sing the Journey hit “Don’t Stop Believin.'”

At first, McIlroy seemed like he was being forced into it, but then the crowd started a “Rory! Rory! Rory!” chant, the piano player hit them with that famous intro, and McIlroy belted away.

“Just a small-town girl!”

Lowry didn’t reach for the mic, but stood there along with his partner, sipping on what appeared to be an ice-cold Michelob Ultra in true Irish form. Even McIlroy took a couple swigs during an interlude to lubricate the vocal cords, of course.

However, those hoping for McIlroy to keep jamming for the tune’s famous chorus will be upset.

Just after the pre-chorus, McIlroy — who was playing his fourth event in the last four weeks — seemed like he had enough. He reached out his and literally dropped the mic before walking of the stage, Lowry in tow.

What started with a “drunken lunch” ended in a mic drop, just as everyone expected.
