Mabelle continued as a small trade center despite a damaging tornado that struck the town about 1923.

[2] On Monday night, April 25, 1955, after performing at the Miller Brothers' M-B Corral dancehall in Wichita Falls, Elvis Presley, bass player Bill Black, and guitarist Scotty Moore headed to another gig in Seymour, a benefit show for the local volunteer fire department.

After fueling up in Mabelle, Elvis and the boys arrived at the Seymour high school auditorium after most of the audience had left, but still managed to perform for the handful of people who remained.
