Maine Sen. Susan Collins isn’t in the habit of taking orders. But when Cyndi Lauper strode into the wings at Darling’s Waterfront Pavilion in Bangor on Friday night, looking for Collins and beckoning her to “Come,” the Republican moderate did as she was told.

“This woman is a hero,” Lauper told the crowd, who were there to see both Lauper and Rod Stewart perform at the Waterfront Concerts. “And she’s my hero.”

Lauper, perhaps best known for “Girls Just Want to Have Fun,” which came out in 1983 when Collins was a legislative assistant to Sen. Bill Cohen, held the beat for a second before making her next point.

“And she’s a Republican.”

The crowd cheered loudly.

The unlikely stage-fellows share a bond because of the work Collins has done “with LGBT homeless youth,” Lauper told the crowd.

“And all the homeless kids. I was blessed to testify on her committee, which was bipartisan,” Lauper said, referring to April 2015 and the Transportation, Housing and Urban Development subcommittee.

“We’re just glad you’re here,” the beaming Collins responded.

And then she tweeted out to Lauper, “I will back you up anytime – on stage or off.”
