It was the first station in Chattanooga to play Jackson Browne's "Running On Empty", as well as Elvis Costello's "My Aim Is True".

On Memorial Day 1978, WSIM sponsored a concert on Lake Chickamauga, featuring female rock singer-songwriter Marshall Chapman.

Expecting approximately 1,000 attendees to show up at the beach by Chickamauga Dam, the station was surprised by as many as 10,000 (estimate according to the Chattanooga Times).

Other live from the studio events included interviews and music with Charlie Daniels, the Nighthawks, Delbert McClinton, Longdancer, and others.

In 1979, the station began simulcasting WFLI's broadcast, effectively ending WSIM's free-form radio reputation.
