On a chilled December night each year, the National Cowboy & Western Heritage Museum becomes that cozy home on the range for Western song, spur-jangling dance and holiday warmth. The 19th Cowboy Christmas Ball welcomes back favorite country singer Michael Martin Murphey to welcome in the holiday spirit with songs inspired as well as those to get your boots scooting across the floor. The ball, 7 p.m. Friday, Dec. 20, has become a tradition in Oklahoma City with old-fashioned western flavor hearkening from the décor and fine art surroundings to the buffet dinner and entertainment. Tickets are $60 (museum members) to $75. Children can attend for $25, which makes the annual Christmas ball a family favorite with plenty for kids, including a visit from Santa. Dress western to get into the spirit of a night that you’ll always remember. The museum is located at 1700 N.E. 63rd St. For more, visit www.nationalcowboymuseum.org.
