What is Kenny Loggins doing these days, other than coming to Hawaii for the 2nd Annual Great Waikiki Beer Festival this weekend? For one thing, he’s been rewriting the lyrics from “Footloose,” the classic 1984 rock musical, for a children’s book about a zoo that will be released in November.

“It came out really cool,” Loggins said on Monday morning, calling from “somewhere about an hour out of Portland, Ore.”

“The idea is that the Zookeeper, Big Jack, lets the animals out on the full moon. They make sure that all people are out of the zoo and then they get out and dance under the full moon. I get to list 100 animals, which works great for children.”

On a somewhat related subject, Loggins’ oldest son, singer/songwriter Crosby Loggins, is the proud father of a baby girl named Pfifer. She’s Loggins’ first grandchild.

“This has launched me into children’s books again, and children’s music,” Loggins said. He’s working on a CD titled “All Join In,” that ties in with the “Footloose” book, but cautions that the music “is not really children’s music, it’s parents’ music.”

“My experience is that the kids are going to hook into something, and they’re going to play it 6,000 times,” he said, “so why not have music that parents can enjoy as much as the kids? I did that with ‘Return to Pooh Corner’ (in 1994) and it’s (sold) over 2 million units now.”

Little Pfifer is also the inspiration for an upcoming album of lullabies. It all began when Loggins encouraged his son to begin singing to her. After Crosby Loggins came up with an idea for a song about Pfifer, Jesse Siebenberg, a longtime friend of the family, contributed a verse about his experiences as a new father. Loggins then wrote a chorus, and the result was the song “Baby Love.”

On an adult note, and “more imminent,” Loggins said, there’s a PBS Soundstage television special that he taped earlier this month in Chicago.

“It’s a 40-year retrospective with Jimmy Messina, Mike McDonald, David Foster, a ton of guest acts,” Loggins said. “Each shoot was 3-1/2 hours long, with a live audience. My daughter, Hana, makes her debut on the show. It’s the first time she and I have sung together. That’s exciting for me, being a proud papa.”

Among the guests are the Blue Sky Riders, a group Loggins started as a side project several years ago with Nashville singer/songwriters Georgia Middleman and Gary Burr.

The trio released their debut album, “Finally Home,” in 2013. They had their second, “Why Not,” ready for release this year but music company BMG expressed interest in releasing an album combining tracks from both projects — and Loggins says that release is coming up.

“That will be our real entry into the marketplace because we only sold around 15,000 units of ‘Finally Home,’ and so we’re still relatively a new act,” he said. “We’ve recorded three more tunes for ‘Why Not,’ so that gives us a ton of other stuff to release in different ways.”

Loggins has been recording since the 1960s and a “name” in the music business almost that long. Hawaii discovered Loggins & Messina in 1972; the duo’s local debut in concert at Andrews Amphitheater was the start of a musical love affair that never ended.

Hawaii embraced Loggins & Messina — “Danny’s Song” and “House At Pooh Corner” continue to be popular — and then followed Loggins through his prolific career as a solo artist. Among his solo hits were a string of soundtrack chart-busters: “I’m Alright” from “Caddyshack,” “Footloose” and “I’m Free (Heaven Helps the Man)” from “Footloose,” and “Danger Zone” from “Top Gun.”

“The first day I wrote ‘I’m Alright,’ I went in, I did the demo, and I knew I had (a hit),” he says. “I didn’t realize that ‘Danger Zone’ was going to be that prominent (in “Top Gun”) but when I saw the movie — ‘Oh my God, here we go again.’”

Beer and wine fans can look forward to hearing many of those classics when Loggins headlines the second annual Great Waikiki Beer Festival on Saturday. The price of admission includes samples chosen from more than 100 beers on tap; wine drinkers have more than 25 wines to choose from. Beer-friendly food such as bratwurst on hoagie buns and kiawe-smoked brisket sandwiches on sweet bread buns will be available for purchase separately.

A portion of the proceeds will benefit the Wounded Warrior Ohana, a local nonprofit dedicated to caring for military personnel.

“I haven’t yet received a request for a benefit that isn’t worthy of some approach, but my belief is you just have to pick something that your heart is most drawn to and go in that direction,” Loggins said. “I’ve had a lot of a lot of good experience with Wounded Warriors. I’ve done a few things for them and it’s the world we live in now. It’s something that needs to be done.”
