The format change became effective on May 1, 1989, and fans soon identified the "KUUL Red Radio" (a jumbo-sized boombox replica) with the station at its live remote broadcast sites.

In December 1985, WLLR briefly gained national attention when a disc jockey played the Christmas song "Grandma Got Run Over by a Reindeer" 27 times back-to-back during the morning show.

WLLR's stage at the Mississippi Valley Fair was featured in the Music Video for "Don't Ya Just Wanna Rock and Roll" by Rodney Atkins.
