Nancy Cartwright, the voice of Bart, has finally scripted an episode of ‘The Simpsons’

But it ain't about Bart...

After being the voice of Bart for 30 years, Nancy Cartwright has finally written her first script for an episode of The Simpsons.

Entitled Girl’s in the Band, Cartwright’s episode will be the 19th in the current 30th season and will focus on Lisa rather than Bart in a storyline based on her own childhood.

“I started playing trumpet when I was 10 — when I was Bart’s age,” Cartwright told TV Insider of the episode. “I was in band in elementary school, middle school, high school. I was in orchestra and switched over to French horn. I was not first chair. But I did have a sense of what I put Lisa through. But in my life, I did speech competitions [instead of band]. I took that and put it into the music world for Lisa, because it was something that was real for me. For writers, your best stuff is what you can pull from your own life.”

Asked if she had ideas for future episodes of The Simpsons, Cartwright continued: “We’ll see. I also co-wrote a romantic comedy. So I’m having fun doing that, and I’m also doing art — I’m painting and sculpting.

“I’d like to do another Simpsons, but we’ll have to see how it falls in with the other things that I’m doing.”

Girl’s In The Band will premiere later this month.

Earlier this year, it was announced that The Simpsons had been renewed for two more seasons, enabling the show to continue its run as the longest-running sitcom on American TV.

The cartoon will return for seasons 31 and 32, which will see it reaching a staggering 713 episodes.

Meanwhile, the show also made headlines when it was revealed that they’d be pulling the 1991 episode starring Michael Jackson after creators argued the episode may have been “part of what he used to groom boys”.
