He was born in Point Level, Garrard County, Kentucky but built a music career in the northern states. His debut radio performance came in 1926 on the National Barn Dance show on WLS-AM in Chicago, Illinois. A prolific composer of folk and country music tunes, the first edition of his 1928 songbook called My Favorite Mountain Ballads sold more than 100,000 copies; later editions brought the total to 400,000. He recorded on Gennett Records.
In 1935 he was working at WBZ-AM in Boston, Massachusetts where he performed with a band that included young singer and banjo player Marshall Jones. Kincaid teased the 22-year-old fellow Kentuckian for always being grumpy when he came to the studio to do the early morning broadcast, nicknaming him "Grandpa" Jones. The moniker became permanent for the future Grand Ole Opry star.
In 1988, the then-93-year-old Kincaid was involved in an automobile accident and sustained injuries from which he never fully recovered. He died in 1989 at the age of 94 in Springfield, Ohio and was interred there in the Ferncliff Cemetery.
