--

On Wednesday morning, Vienna's Jammin' Java got an unusual phone call: Nick Jonas was looking for a venue for an impromptu performance later that night.

The 18-year-old, most famous for his membership in the band The Jonas Brothers, is in town to perform at the Motown Tribute show at the White House on Thursday night.

Around 2 p.m. Wednesday, Nick Jonas sent a tweet to his 2 million Twitter followers letting them know he would be playing a free show at Jammin' Java. By 2:30 p.m., his fans were converging on the venue, and the line was growing.

Elizabeth Zorn, a high school student from Maryland arrived at 3:45 p.m. She bought a snuggie at the Walgreens next door to keep warm. "It's never too cold for Nick Jonas," she said.

Wristbands were handed out and at least 70 people were turned away after the maximum capacity was reached.

Allison Kann arranged a ride from Woodbridge after seeing the announcement on a friend's Facebook wall. In the car, she drew a picture of Jonas. She passed the picture around in line, asking everyone to sign the back and gathered hundreds of signatures. She planned to give it to him after the show.

Jonas took the stage shortly after 11 p.m. in a performance modeled after VH1 Storytellers. The show was also filmed by Cambio.com, a video website owned by AOL, Patch's parent company.

Jonas and his friend and bandmate John Lloyd Taylor discussed how some of his most popular songs were written and how they have developed over time. After about an hour, Jonas and Taylor finished up their set, but not before he thanked the fans for their support and "all the parents, for letting your kids stay out so late."
