Cunningham said that due to a scheduling conflict Houser had to cancel his show. âMr. Houser has booked another project and cannot perform at Spring into Summer due to COVID-19 regulations put into place by said project,â Cunningham said in the release. âAlthough we understand the situation Mr. Houser was put in, it will be very difficult to replace him with only five weeks left. Please be patient with us as we look for a new headlining artist and keep an eye out for the big announcement.â Cunningham added in the release that while Oak Grove Tourism is confident it will find a replacement for Houser for the 13th Annual (Take 2) Spring into Summer Festival, the event will continue with or without a headlining artist.
