Part-time rocker Rep. Collin C. Peterson can no longer recall which iteration (the fourth, maybe?) of “The Amendments” he’s playing in these days.  

But the Minnesota Democrat fully expects to have a blast Thursday night, when the lawmaker-led band featuring a revolving roster of current and former pols takes the stage at Cantina Marina (600 Water St. SW).  

The show, headlined by “Blame It On Jane,” a group of ex-congressional aides and lobbyists routinely on the convention circuit , is scheduled to run from 7 p.m. to 11 p.m.; no cover charge.  

Per Peterson (lead singer/rhythm guitarist), he and current band-mates Tennessee Republican Stephen Fincher (bassist), ex-Missouri Republican Rep. Kenny Hulshof (percussion/keyboards), and former Hulshof Chief of Staff Manning Feraci (lead guitar) are looking forward to dazzling concertgoers with the latest cover tunes they’ve added to their sonic toolbox, Lynyrd Skynyrd’s “Sweet Home Alabama,” and Roy Orbison’s “Only the Lonely.”  

Other former lawmakers that have cycled through the constantly evolving troupe include: politician-turned-pundit Joe Scarborough, R-Fla., as well as Republicans Dave Weldon of Florida, Thaddeus McCotter of Michigan and Jon Porter of Nevada.
