When Mike Rowe crashed a barbershop quartet

A barbershop quartet is just a few moments into its opening number when a man walks out of the shadows at the edge of the stage and heads for the mic. more

It is Mike Rowe, the TV host, wearing a sly grin. He eases into the middle of the four singers as if he had been part of the group all along.

Mike Rowe slides into the middle of a song that has already started.

The crowd looks puzzled, then starts to smile. When he opens his mouth and sings along, people laugh. It looks like exactly the kind of joke they would expect from him, a famous guy goofing around in somebody else's act.

A few seconds later, the joke is over. The song is the classic "Sweet and Lovely," and Rowe isn't clowning. He has meant it from the very first note.

A barbershop quartet is just a few moments into its opening number when a man walks out of the shadows at the edge of the stage and heads for the mic.

What comes out is a deep, booming bass. Fans love one low note in particular, and the faces in the room when he lands it. Another favorite detail is the way his eyes light up while he sings.

The quartet seems to be having as much fun as the crowd. One barbershop fan wrote that they had never seen anyone as happy to ring a chord as Rowe.

The singers share the stage with their new bass.

A lot of people asked who knew he could sing like this. One person did. They heard him sing with his high school quartet years ago and say he hasn't changed a bit. He is still warm and modest, and he still loves barbershop.

By the final chord, the room that laughed at him a couple of minutes earlier is cheering for him. He walked on as a gag and stole the show.

By the end of the song, the laughs from the crowd have turned into cheers.

One fan has the nicest story of all. They spent about 20 minutes with Rowe over drinks later that night and call him gracious. When the fan's phone died, they say, Rowe snapped a selfie and emailed it over.
