Ron Howard’s Son-in-Law Tim Completes Epic 365-Day Song Challenge: ‘A Pure Labor of Love’ (Exclusive)

Tim Abou-Nasr is spreading joy through music as he completes his epic 365-day song project.

The son-in-law of filmmaker Ron Howard has been posting daily covers of genre-spanning songs for a full year as of Monday, July 21, capped off with a rendition of Green Day’s 1997 hit rock ballad “Good Riddance (Time of Your Life)” — the first song he learned to play on guitar, at 13 years old.

Speaking with PEOPLE about the massive undertaking, the actor and longtime musician, who is married to Ron’s daughter Paige Howard, says he’d “been toying around with trying it for a couple of years” before starting.

“I started to notice that I had this massive repertoire that I was building, but didn’t have anywhere that I could show anyone,” explains Abou-Nasr, 37. “It was like, I could do it in person for people, but I didn’t have a place where I could show it to the world.”

And for him, social media “always felt awkward” when he considered posting on his own personal feed, leading him to make an Instagram account just for his music.

“I was always kind of apprehensive about social media,” Abou-Nasr says, “but it’s just because I didn’t ever know what to post.” Once he saw it as “a challenge for my accountability,” though, he envisioned the project as “a way I could sing all these songs I’ve learned over the past lifetime.”

Among the artists Abou-Nasr has covered include Barenaked Ladies, Elton John, A-ha, Nirvana, Johnny Cash, the Goo Goo Dolls, Ben Folds Five, Dolly Parton, Yusuf/Cat Stevens and Coldplay — as well as some of his favorite showtunes and songs by one his most-loved bands, The Beatles.

As for the most challenging songs, Abou-Nasr says “the ones that are the most time-consuming” are those that involve harmonies, “both in having to edit the videos and having to learn the different harmony parts” — like when he’s “singing all four of The Beatles’ parts.”

Of whether he will continue past his initial year-long goal, the musician tells PEOPLE that while his “original” plan was to take a “break,” he has developed a fan base of “listeners all over the world” over the past 365 days whom he now feels loyal to.

“I have this couple in London that writes me sweet messages about how they listen to my song every day while they have their coffee,” Abou-Nasr says. “And there’s people in Canada, and then obviously in Omaha where I’m from, my mom and my grandma are like, ‘Don’t stop, we love it.’ So I think I may continue it [in some capacity].”

Ron, 71, tells PEOPLE that his son-in-law’s project “reflects his relationship to pop music and music of all kinds, because it’s a pure labor of love.”

“I’ve got a lot of talented family members, between my kids and their spouses and now grandkids, but he’s the first professional musician, and he’s done it all,” the celebrated filmmaker says. “[Tim has had] years performing in restaurants and on cruise ships and busking in New York. I saw him one time piling up some cash, having fun doing that.”

“So in and around his acting, he’s always loved music, and he’s kind of a chameleon,” Ron continues. “I’ve also seen him perform onstage, doing musicals. He’s a very talented guy and a great husband to Paige, and we really love him.”

“But he’s the first musician [in the family], so it’s really interesting to see somebody who can just play and there’s just no effort to it,” Ron adds. “There’s nothing but joy that comes out of him and the instrument he’s playing when he starts playing a song. Plus, his taste in music is exquisite.”
