Opal Jean Amburgey (March 6, 1925 – August 19, 1995),
known professionally as Jean Chapel, was an American country singer and
songwriter. She recorded for several record labels and wrote over 400 songs,
more than 170 of which were published in her lifetime.

They moved to Atlanta, Georgia in 1940 to sing on WSB
Barn Dance; she began using the nickname Mattie at this time. Her sister Irene
would later record with Columbia Records under the name Martha Carson. At age
15, Jean had already performed at literally hundreds of shows, appeared daily
on radio stations, sang on barn dances, became a member of t
he Coon Creek Girls,
and was about to begin what she would be most remembered for – writing songs.

In 1947 she married Salty Holmes, and in 1950 they moved
to Chicago, Illinois to appear on National Barn Dance on WLS-AM. Soon Jean
began appearing on the Grand Ole Opry opposite Holmes as Mattie & Salty
under the name Mattie O'Neil.
In the early 50's, Jean would record solo for Hickory
Records under the name Opal Jean; record with her two sisters for the King
label
in 1951 as the Sunshine Sisters; and officially become, Jean Chapel, in
1956 when signing with Sun Records to sing rockabilly songs like "I Won't
Be Rocking Tonight" and "Welcome to the Club" which was issued on
the B-side of an Elvis single. Sun promoted her as the Female Elvis, but the
nickname stuck more successfully to Janis Martin. In addition to the Sun label,
Jean recorded for Capitol, London, Challenge, Smash, and RCA Records.

Chapel divorced Holmes and moved to Nashville, where she concentrated on writing through the '60s. She became neighbours with Tammy Wynette, who began recording Chapel's songs and did a duet with her called "Crazy Me." Wynette was also briefly married to Chapel's brother.

Chapel died August 19, 1995 in Port Orange, Florida.
