Jim NaborsJim Nabors wasn't born or raised in Indiana, and he doesn't live there. Yet that hasn't prevented him from becoming one of the state's favorite sons. Singing "Back Home Again In Indiana" before the vast majority of Indianapolis 500 races over the past 40 years will do that for a guy.

But this year, the 81-year-old actor and singer won't be able to make the trip from his home in Hawaii to Indy, due to a scheduled heart surgery, according to USA Today. Apparently the tradition is important enough to the folks that run Indianapolis Motor Speedway, that instead of calling John Mellencamp, they have dispatched a video crew to our 50th state to record Nabors singing the song.

According to the report, Nabors has performed the song before every Indy 500 since 1987 except for the 2007 race, which he also missed for health reasons. Nabors also sang before the 1972-1978 races and two additional times in the 1980s, according to WTHR.
