Why is Joe Bonsall retiring?

Joe Bonsall, the tenor singer of The Oak Ridge Boys, has made the difficult decision to prioritize his health and step away from touring with the iconic country music group. In an exclusive announcement to PEOPLE on Wednesday, the 75-year-old singer revealed that he is dealing with a neuromuscular disorder that has progressed over the past four years, making walking impossible.

Bonsall expressed gratitude for the 50 years he spent on the road with The Oak Ridge Boys, acknowledging the band, crew, and staff for their constant love and support. Despite the challenges he faces, he remains thankful and appreciative of the prayers and well-wishes from fans. Bonsall urged his supporters to continue praying for him.

During a concert in Greenville, Mississippi, on December 30, The Oak Ridge Boys introduced Ben James as Bonsall’s official replacement. Bonsall spoke highly of James, emphasizing the need for love and encouragement for the young singer. He acknowledged the differences in their sounds but praised James for bringing a wealth of talent to the table. Bonsall expressed confidence in The Oak Ridge Boys completing the Farewell Tour without him, trusting in the journey ahead.

Ben James, at the age of 27, was introduced to the band in 2022 during a concert in Wheeling, West Virginia. Reflecting on the significant moment when Joe Bonsall handed him the mic, James expressed awe and appreciation, noting the impact of The Oak Ridge Boys’ timeless song “Elvira” on his upbringing.

The Oak Ridge Boys are currently on their American Made Farewell Tour, scheduled to run through September. The tour commemorates the 50th anniversary of the band’s current lineup playing their first show together. Named after their hit song “American Made,” released in 1983, the Country Music Hall of Famers are treating fans to beloved classics from their extensive career during these farewell shows.

In a statement shared exclusively with PEOPLE in September, Joe Bonsall reflected on the incredible journey of The Oak Ridge Boys, expressing amazement at the longevity of the group. He highlighted the challenges they’ve faced over the decades but emphasized their commitment to doing things right and the blessings they’ve received from God. Despite stepping back from touring, Bonsall’s impact on the band’s legacy remains indelible, with The Oak Ridge Boys continuing to share their timeless music with fans across the nation.
