Winnipeg musician enjoys command performance for actor Sean Penn

Musician Keri Latimerhas played plenty of big shows in her life, but nothing like the performance she gave last weekend at a Winnipeg restaurant.

It all began Saturday when she received an email while lounging by the pool at a friend's house. It contained an invitation to perform later that evening at a private party hosted by actor Sean Penn.

"It was out of the blue," saidLatimer, a singer/songwriter, guitarist and theremin player who has toured internationallywith her current band, Leaf Rapids, as well as her former band Nathan.

The email was from the associate producer of the filmFlag Day, which stars Pennand is being shot in Winnipeg. A fewweeks earlier, the producer had seen Latimer and Leaf Rapids on stage at the Burton Cummings Theatrewith 10-time Grammy winner Bobby McFerrin.

"He saw our show and wondered if I would come in a couple of hours to a party Sean Penn was hosting and back up a young singer on guitar," said Latimer.

The young singer was 13-year-old Jadyn Rylee, who plays Penn's daughter in Flag Day. Shehas become famous online for her YouTube channel, where her covers of popular songs have garnered more than 50 million views.

Latimer was hesitant at first. While she plays guitar, she doesn't usually play it on stage.

But her husband Devin, who performs with her in Leaf Rapids, called them back and said "Yes." Once they sent her the songs, Latimer realized this was something she could do.

"It was just one of those crazy random calls that you just go, 'Oh my God.I just have to do this.'"

So the couple raced over to Mona Lisa restaurant on CorydonAvenue, wherePenn was hosting a midway-through-the-shoot party for the cast and crew. The two-time Oscar winnerwas sitting out on the patio when they got there.

"He introduced us" saidLatimer. "And then he was sitting in the front row. It was a very lovely experience and a little terrifying. But exciting!"

Latimer backed Ryleeon Nothing Else Mattersby Metallica and Shallowfrom the movie A Star is Born.

"It was so funny how calm everything was," she recalled. "I wasn't nervous or anything. Everyone was very naturaland Sean was very nice."

Latimer describes Penn and the other actors as "regular people." The group included fellow actor Josh Brolin andPenn's real-life daughter Dylan Penn, who plays the grown-up version of Penn's daughter in Flag Day, taking over from Rylee's younger portrayal.

As for the young singer, Latimerdescribed her in glowing terms.

"Jaydn'sthe same age as my daughter, and she was a complete sweetheart and a really talented singer."

After the performance, Latimer and her husbandmingled with the others at the party, sipping sangria.

"It was nice, because I've done some movie scoring," she said. "Just the chance to talk to producers of bigger movies you never know what it can lead to."
