Musicians to perform for Bob Wills Day; Brown leading effort Posted: Friday, March 20, 2015 2:26 pm OKLAHOMA CITY – Fans of “Western swing” music should mark March 25 on their calendars. That’s the date of the annual Bob Wills Day celebration at the Oklahoma State Capitol this year. Fiddlers and other musicians will perform from 9 a.m. to noon in the House of Representatives chamber, and from 1 to 3 p.m. in the fourth floor rotunda. “All Oklahomans are invited to come to the Capitol and enjoy the music and camaraderie,” said state Rep. Mike Brown, D-Tahlequah, event coordinator.
