There may be some singing, but Jeffre says don't call it a concert.
"We may sing an acappella song — possibly two, probably not much more than that," Jeffre said. "We don't want to give people the wrong impression."
Jeffre, along with members Nick and Drew Lachey and Jeff Timmons, plan to attend a rally for Jeffre on Saturday afternoon and appear that night at a nightclub where admission will be a donation of at least $10 to Jeffre's campaign.
Jeffre is one of seven candidates in the nonpartisan Sept. 13 mayoral primary, which will determine the two candidates to be in a November run-off. Jeffre has campaigned actively and has participated in several debates, but believes he has not been taken seriously.
He wants the group to sing their hit "Invisible Man" at his rally "dedicated to some local media outlets that ignored me."
