That's the Rev. Seth Whitney, by the way

Seth Whitney will have duties that extend beyond playing bass this weekend.

“I don’t want to be known as a reverend,” said Whitney, the bass player for Band of Heathens and, yes, an ordained minister.

“It’s ironic that our name is Band of Heathens and I am a reverend.”

Before the band’s concerts Wednesday at the State Theater, Seth will be the officiant at the wedding of his father, Bruce Whitney, the musical director of Harlequin Productions, to Bonnie Butler.

“It’s a little weird,” Seth said, “but it’s actually really cool. I am so happy for my dad.”

The wedding is also happening at the theater, owned by Scot and Linda Whitney who are Seth’s uncle and aunt and Bruce’s brother and sister-in-law.

The timing of the wedding is no accident.

“We were thinking about when the most relatives would be in town, because they are spread all over the place,” Bruce Whitney said. “Almost everybody was going to be here at the time Seth would be here with the band.”

Seth Whitney’s ministerial credentials are from the Universal Life Church. He saw an advertisement in Rolling Stone magazine and mailed away for the certificate for fun.

He’s since performed several wedding ceremonies.

“It’s a very nontraditional, nonreligious thing,” he said. “It’s just all about the love.”
