This year's Indy 500's pre-race festivities will be highlighted by what actor Jim Nabors says will be his final singing of "Back Home Again in Indiana" at the track. The 83-year-old Nabors has performed the song nearly every year since 1972.

In 1972 there came an unexpected opportunity to be the opening act for the Indy 500. "It's really remarkable thing for me. It's the highlight of my year because it's 500,000 of my closest friends and they do make me feel like I'm their best friend," Neighbors said.

Coverage of the 98th Running of the Indianapolis 500 begins at 10 AM Sunday morning on ABC TV.
