(AP)—Researchers have recovered and digitized what experts say is the oldest playable recording of an American voice and history's first-ever recorded musical performance.

Also included: the first recorded blooper.

The recording was done on a sheet of tinfoil on a invented by and made in St. Louis in 1878. It opens with a short cornet solo and is followed by a man reciting nursery rhymes.

Near the end of the 78-second recording, the man laughs after messing up one of the words to "Old Mother Hubbard."

The tinfoil and the newly digitized recording is being presented Thursday at a museum in Schenectady (skeh-NEHK'-tuh-dee), N.Y., where Edison founded the Co.

Experts at California's Berkeley Lab recovered the recordings using technology developed for the project.
