A multisided record is a type of vinyl record which has more than one groove per side. This technique allows hidden tracks to be encoded on LPs, 45 rpms and 78 rpms. On a disc that has a multi-groove, whether the listener plays the main track or the hidden track depends on where the stylus is cued. The most frequently cited example of a multiple-groove record is Monty Python's infamous "three-sided" Matching Tie and Handkerchief album, issued in 1973. One side of the album was "normal"; the other contained a pair of grooves, each of which held different material. Another memorable example of a multiple-groove recording was the 1980 flexi disc entitled It's a Super-Spectacular Day issued by MAD magazine. The disc played a standard introductory section about the start of a wonderful, "super-spectacular" day, then produced one of several different comedic "bad" endings to that day, involving such topics as alien abduction, zits, street violence, and the horrors of a visiting mother-in-law. Other uses to which multiple-groove recordings have been put include various games where the outcome is determined by which of the record's multiple grooves is played.
