The cast of A Prairie Home Companion will be on a cruise through Southeast Alaska April 14-21st. Garrison Keillor has graciously offered to do a small show for KTOO listeners, with himself and Rich Dworsky while they are in Juneau on July 16th. The performance will be at Centennial Hall from 5 p.m. – 6:30 p.m., with pictures and photographs from 6:30-7 p.m. At Mr. Keillor's request, we are limiting attendance to 300. To be fair with ticket distribution, we will conduct a drawing -- if your name is drawn, you will have the option to buy two tickets. Ticket price is $30 each.
