For musical entertainment before the start of the race, the Purdue All-American Marching Band has been the host band of the race since 1919. In 1946, American operatic tenor and car enthusiast James Melton started the tradition of singing "Back Home Again in Indiana" with the Purdue Band before the race when asked to do so on the spur of the moment by Speedway president Tony Hulman. This tradition has continued through the years, notably by actor and singer Jim Nabors from 1972 until 2014. Nabors announced in 2014, citing health-related reasons, that the 2014 Indy 500 would be the last at which he would sing the song. In 2015, the a cappella group Straight No Chaser sang the song before the race, and in the two races held after Nabors' retirement (and before he became the regular singer), the singing of the song was done on a rotating basis, with the Spring 2014 winner of The Voice Josh Kaufman performing in 2016. However, the Speedway has returned to a standard singer starting in 2017, with Jim Cornelison doing it for three races as of the 2019 race.
