Unknown Artist – They're At The Post

From Wikipedia: Parallel grooves

Also known as concentric grooves, it is possible to master recordings with two or more separate, interlaced spiral grooves on a side. Such records have occasionally been made as novelties. Victor made one as early as 1901. Depending on where the needle is dropped in the lead-in area, it will catch more or less randomly in one of the grooves. Each groove can contain a different recording, so the record "magically" plays one of several different recordings.

In 1975 Ronco UK released a parallel groove game called "They're Off," which featured four 12-inch discs each containing eight possible outcomes on a horse race. It featured Noel Whitcomb, a well-known horse-racing commentator of the day and the game revolved around betting which "horse" would win the race on that occasion. This appears to have been based on a Canadian product called "They're at the Post" by Maas Marketing, which is more or less the same game with different recordings on the discs to reflect the target market.
