BILL HAYMES grew up on a small Missouri dairy farm, where family jam sessions introduced him to an eclectic mix of music.  He attended Rice University, then moved to Maryland, where he played the college coffeehouse circuit while developing his songwriting.           In the early '70s, he recorded Bill Haymes - USA, featuring songs written about his experiences on the road.  He made his first trip to the Kerrville Folk Festival in 1976, and was a New Folk winner there.           Haymes then moved closer to home, locating in Little Rock, where he continued his career as a touring musician.  He started teaching songwriting, too, working with children in an NEA-funded Artists in Education program.  He also taught a class at a summer enrichment program for gifted teenagers, called the Arkansas Governor's School.  In 1982, Bill became a featured artist in the Starlight Concert Series, presenting six to eight outdoor concerts each summer in Arkansas state parks.           In the late '90s, Haymes relocated to Nashville.  He continues to tour nationally, as well as performing in his new hometown, at the Bluebird Cafe and other venues.  Bill has toured in South America, guested on Garrison Keillor's "A Prairie Home Companion" and on Tom May's nationally-syndicated "River City Folk." His latest album is titled Brave New World.
