Debbie and Harry Vann of North Carolina had just finished exchanging their wedding vows at White point Garden on Saturday when they got an opportunity to have their first dance a little ahead of schedule.

The couple and their wedding party were in the park’s gazebo when Charleston jam rock band Dead 27s showed up to play a set of tunes as part of their One-Day Magical Mystery Tour across the Lowcountry.

With rain threatening, lead singer Trey Francis asked the couple if they would mind if the band played a song or two.

“Why don’t you pick something right quick,” Harry Vann replied.

“OK, and we’ll dedicate this one to you,” guitarist Wallace Mullinax said.

In no time, the band was serenading the Vanns with Van Morrison’s “Crazy Love.” The wedding party sang along and the newly married couple did a slow dance as passersby stopped by to check out the impromptu concert and snap some photos.

The Dead 27s came up with the idea of a multi-stop, one-day tour as a way to build some excitement and raise some money for a planned studio stint in July to record some new music.

The four-piece band began the day at noon with a concert at the Windjammer on Isle of Palms, moved on to High Thyme on Sullivan’s Island and cycled through three more stops in Mount Pleasant before ending up at The Battery and White Point Garden. Their next stop was a private party on James Island and then a two-hour gig at Rita’s Seaside Grille on Folly Beach. After that, they weren’t sure where they would end up, but they were still pumped to play.

“I don’t think I’ve ever played this many shows in a row,” Mullinax said. “But it’s been really cool.”

The Vanns were more than happy for the unexpected interruption.

“They were really good,” Harry Vann said.

“And we got our first dance!” his wife interjected with a smile.
