Some minor guitar-amp difficulties slowed down the start of Shawn Colvin’s show Tuesday at the Maine Center for the Arts. But after a few small repairs, she was up and running.

For more than an hour and a half, Colvin sang, told stories and talked with the audience about a diverse range of topics – maxi pads, the World Trade Center attack, potty training. The (relatively) new mom even sang her 3-year-old daughter’s favorite song, “I’m a Super-Duper Pooper,” from the “It’s Potty Time” video.

The crowd seemed to enjoy it, though I would’ve preferred less talk and more music. Grown-up music, that is.

When she did sing, her strong, clear, lilting voice made up for it. She played the Grammy-winning “Sunny Came Home” and cast a spell with her remake of The Police’s “Magic.” But she almost seemed beyond that, like those days are behind her.

Watching Colvin on the stage, it was easy to see why her long-awaited recent release is titled “Whole New You.” She didn’t look like the Shawn Colvin I remembered. With cropped blond hair and a charcoal gray, empire-waist dress, she looked more Julia Roberts-meets-L.L. Bean than edgy folk.

In an interview on her Web site, Colvin said, “I think parenthood is a part of what’s going on in all, these songs [on ‘Whole New You]. I’m married, I had a child, and we are a family.”

That’s where her focus is now. Even when she was singing her heart out in “Shotgun Down the Avalanche,” she seemed distracted, like she wished she were in Texas, where she lives with her daughter and husband.

This show wasn’t totally about Colvin, however. Her music seemed introspective, but she reached out to the audience in other ways, asking for requests during her three-song encore and talking with, not to, the audience.
