By 1959, the doubleheader and tripleheader formats had been mostly abandoned in favor of one longer feature. In addition, support races were filling the docket to improve the show for fans. The event moved to the Indiana State Fairgrounds oval in 1972-1973 and was held as two 50-lap features. But the 1973 Night Before the 500 was plagued by rain, much like the 1973 Indianapolis 500. The Night Before the 500 twin 50-lap Midget races were rained out on Sunday May 27 and initially rescheduled for June 17. However, a scheduling conflict saw the event rescheduled a second time until July 4 and the race was renamed the "Firecracker Fifties." On July 4, the event was cancelled due to heavy rain, and never rescheduled. After that much-maligned event, the Night Before the 500 returned to IRP the following season.
