Clay Walker was named the Country Radio Broadcasters' artist humanitarian of the year during Wednesday morning's (March 5) opening session at Country Radio Seminar in Nashville. Walker was cited for his continuing work in funding research, raising awareness and providing education for those battling multiple sclerosis. Walker was diagnosed with MS in 1996 and is now in remission. In 2003, he formed Band Against MS, a nonprofit organization that has raised more than $1 million for MS research. ... Also during the morning session, the CRB honored three radio stations with its annual radio humanitarian award -- WFLS/Fredericksburg, Va. (small market), WIVK/Knoxville, Tenn. (medium market) and KYGO/Denver (large market). View photos of Clay Walker at Country Radio Seminar.
