MAGS MCCARTHY AND DR. BRUCE LEVINE RING IN HOPE WITH POWERFUL NEW SINGLE “RING THAT BELL” OUT MAY 2ND

An extraordinary collaboration between artist and scientist shines a light on CAR T-cell therapy and the power of perseverance.

Internationally acclaimed Irish country music artist Mags McCarthy is set to release her most heartfelt and powerful single yet, “Ring That Bell”, on May 2, 2025. In an unexpected and moving collaboration, Mags has partnered with world-renowned scientist Dr. Bruce Levine, a pioneer in cancer immunotherapy, to co-write a song that gives voice to cancer warriors and celebrates breakthroughs in treatment that are changing lives.

The single follows the breakout success of Mags’ recent hit, “Our Song”, which became

the #1 Best Seller on Amazon, has garnered over 1 million views on YouTube, and is

climbing the U.S. country charts—a testament to her growing global fan base and

ability to tell deeply personal stories that resonate far and wide.

“Ring That Bell” tells the emotional story of a cancer patient facing relapse and the fierce advocacy, support, and groundbreaking science that offer new hope. At its heart is the powerful symbolism of ringing the bell—a tradition in many cancer centers marking key milestones like the end of treatment, good news, or moments of gratitude and encouragement.

“I really enjoyed writing this song with scientist Bruce Levine. Cancer has affected a lot of people's lives. This song is very special and I hope it will give people hope when they are going through their journey. We should never give up the fight no matter how hard and dismal things may look. We should always try and find a way to give people hope. CAR T-cell therapy has given people that chance to survive with certain types of cancers. I want to say a special thanks to all the scientists, doctors and nurses who treat patients every day and who fight every day to keep us alive. I hope this song will bring awareness and hope for all the cancer warriors out there. Thank you! Lots of love, Mags” — Mags McCarthy

A heartfelt tribute to the power of perseverance, community, and innovation, “Ring That Bell” draws on real stories from families whose lives have been changed by CAR T-cell therapy, a revolutionary treatment that engineers a patient’s own immune cells to target and kill cancer. Dr. Bruce Levine, whose pioneering work helped bring the first FDA-approved CAR T-cell therapy to market, co-wrote the song with Mags, offering a unique blend of scientific inspiration and musical storytelling.

“The song Ring That Bell speaks to the community of support all patients deserve, and the community of fellow patients on their own journey through cancer.” — Dr. Bruce Levine

“We owe our deepest gratitude to the patients and families who have trusted science and placed their faith and hope in us by volunteering for clinical trials to advance the development of new therapies for cancer.” — Dr. Bruce Levine

The single arrives alongside deeply moving stories of the many patients who have received CAR T-cell therapy after traditional treatments failed. From around the world, these brave children, adults, and their families share a common message: CAR T saves lives. The touching photos and videos accompanying the release show children ringing the bell, not just as a milestone, but as a declaration of survival, resilience, and the promise of tomorrow.
