Haven't received a schedule yet, but the line-up for high schools on Saturday is posted below. Keller Central usually does a great job with their website, so I expect more information to be posted there soon. The schedule and program information on their website still currently reflects the 2018 competition, however, they do have live stream information for 2019 posted. There is a fee associated and purchasing a ticket for the live stream can be done so here: https://lonestarinvitationalshowchoir.info/buy-ticket/.
