The original OKeh Laughing Record, first released in 1922, features a man and woman laughing uncontrollably in response to a musician playing out of tune.
Jacob Smith wrote about the Okeh Laughing Record extensively in his blog Vocal Tracks in 2008.
This is the Beka Laughing Record, the German version of the OKeh Laughing record. Or was it the other way round?
The record was also featured in the 1955 Walter Lantz cartoon Sh-h-h-h-h, the last short directed by Tex Avery.
