Found this on a page about early television programming in Los Angeles, California. Seems Jimmy Scribner worked for radio and then moved to television:

Anyone remember Sleepy Joe?

Sleepy Joe was developed by Jimmy Scribner for the Mutual Radio Network in 1948, and in September a televised version debuted at 6:30-6:45pm, every day but Sunday and Wednesday on KTSL in Los Angeles. It was the pioneer local children's show on the Don Lee station, moving to KECA one year later, he continued the series at 6:45-7:00 pm Saturday and Sunday until December of 1949, when it was kinescoped for the network in October. In 1951, scribner syndicated a 15 minute film version of Sleepy Joe with puppets dramatizing his stories, supplying all the voices for the characters.

Scribner, a master of Afro-American dialect and a radio veteran was born in Norfolk, Virginia. After working in various radio stations in the east and mid-west, in 1945 he moved to Los Angeles to be on KHJ. Literally a one-man show, the versatile actor played an entire community of blacks in Chicazola, "way down south", eventually playing twenty-two different parts. "Uncle Remus" storytelling was just enjoying a resurgence due to Disney's success with "Song of the South".

Sleepy Joe premiered October 3, 1949. The last program aired October 28 1949.

This show was produced by Jimmy Scribner, who also acted in blackface as a rural spinner of yarns who also tended his corn patch and assorted small animals, including a dog, two ducks and a pair of de-skunked civets (!) Located supposedly in the deep south, he would spin his tales to a young girl named Gayle, played by Scribner's daughter Gayle Scribner. Telling tales, fables and legends about animals, he would sometimes ad-lib the entire story. Aimed at youngsters four to fourteen, Scribner cleverly interwove little maxims in the yarns, such as how brains can beat brawn.

Distributed by Aurora Films from 1951-1960 in syndication.

Performing in blackface would be considered politically incorrect today, in America, at least. I still wonder about the musicianship in the program I listened to.
