“Monster Under My Bed.”

“Bear Eating a Pickle.”

“Funk-a-Zoo.”

“If I Was a Fish.”

These are song titles. “Eleanor Rigby” and “I Will Always Love You” they are not. They are silly. On purpose.

And that completely and happily suits members of The Plants, a Philadelphia-area band that caters to the whimsical — and sometimes serious — musical appetites of little kids. The Plants will be the opening act for the Chestnut Hill Community Association’s Pastorius Park concert series on Wednesday, June 17, at 6:30 p.m. The Plants are on a mission to bring funk, doo-wop and folk tunes to the tiny-tot masses. The concert is free.

More than a decade ago, the four members of The Plants — professional musicians all — were playing in conventional bands, performing for adult audiences. But early on, they recognized their wacky streak. Around the winter of 2010 they were snowed in during a massive storm and just started writing songs.

“We found ourselves making up really silly fun songs on the spot,” explains Gabriel Romano, who plays guitar in the group primarily, but also bass, banjo and mandolin. “We liked to improvise and come up with these silly lyrics, and a lot of those things stuck. We enjoyed it a lot. So, that’s where it started. A couple of us suggested that we turn them into real songs. So we wrote a few real songs, and we released an album in 2011. We were shocked at how quickly it picked up.”

The band really took off when Kathy O’Connell began playing their tunes on WXPN’s “Kids Corner.” After the first album, “Sprouting Out,” dropped, The Plants’ tunes were suddenly on heavy rotation on the show. And before they knew it, they were playing gigs at the Mann Center for the Performing Arts and the Kimmel Center. After years of playing adult music, trying to get into bigger venues, it came as a shock.

“Pretty much immediately,” Romano says, “there we were.”

Joining Romano on the Pastorius Park stage will be Dan Peters, who primarily plays saxophone, but also guitar and bass; Adam Monaco, who plays bass, mandolin and guitar; and drummer Winston Johnson.

The first three perform vocals, sometime leading and other times chipping in on harmony.

Though the band gravitates toward funk and folk, doo-wop and pop also play starring roles.

“We also have songs that are a bit more topical, and a little bit about driving home a good message,” Romano said. “We have a newer song, “Best Version of Me.” It’s about always waking up and trying to be better every day. But we have three and a half albums worth of songs, so there’s plenty to choose from. We’ve got songs about being the new kid in school and a rocket pack journey. We have a song about a giant dragon who lives on an island full of gold. We’ve got songs about intergalactic insects and their voyage through space. So, we’ve got a lot of different imaginative stuff. Our goal is to get kids engaged and come along for the ride.”

Listening, though, is only part of The Plants experience. When the band plays live shows, they lean heavily into dance music. For instance, they have a tune called “The Spinaround,” which, Romano says, is always a hit. “It comes with a disclaimer,” he adds, “that it’s OK to stop spinning, but ‘The Spinaround’ is always a fun time.”

The Plants’ performances might not work as well if they were completely aimed at children. The band is family-friendly — and that means adults, too.

Romano said, “We’ve had a lot of parents who have come up to us and said something like, “We’re so glad we have your CD in the car — this is when CDs were a thing — because we actually enjoy it as well. We take a lot of pride in that.”

Like other band members, Romano had no kids of his own at the beginning, but he does now. He understands how important it is to appeal to the entire family. Not every album that Romano’s kids like appeal to him.

“Sometimes, I think, I can’t listen to that song another time,” he said. “So, we try our best to keep things fun and imaginative, but also real and trying to make it an enjoyable listening experience.”

The Plants’ performance is presented by Kathy Krebs and Rachel Reilly with Elfant Wissahickon Realtors. The presenting sponsor of the concert series is Temple Health Chestnut Hill Hospital.

Pastorius Park is located at Lincoln Drive and West Abington Avenue.
