but every copy of Matching Tie and Handkerchief has three sides. The second side of this album has two sets of grooves, and depending where you place the needle it follows one path or another, presenting one of two entirely different programs.
There’s a “horse race” 78 on the wall in the record shop that does the same thing – each time you can’t be sure which horse will win until the end. It’s called a “double groove” record or a “parallel groove” record.
You can find the same effect on several Victor 78s (“puzzle records”) and also on occasional modern pop records, where it usually provides a hidden track. De La Soul’s “Brain Washed Follower” was first presented as a hidden track on a 12″ single, for instance.
