At 83 years old, though, we can't really blame Nabors, who travels to Indy from his home in Hawaii, for giving up the gig. He missed the 2012 race and the 2007 race because of health-related issues.
"I'll see you all in May; but I've come to the conclusion that my health doesn't permit me to travel very much anymore. So I'll be retiring from singing 'Back Home Again' at the Indy 500 after this year," Nabors said in a statement. "I want to give a special thanks to everyone; and particularly the Hulman-George family, who have a special place in my heart and are my wonderful friends. I've loved every minute of it."
As it stands, Indianapolis Motor Speedway hasn't said who will replace Nabors in 2015, although according to NBC Sports, the track does plan to honor the long-time singer.
