Pierre Schaeffer in France did a lot of experimenting with locked grooves on records before the tape recorder became widely available. AFAIK he didn't use it for looping of traditional melodies & chords, etc but to create pieces of "musique concrete":
Interesting stuff. But the locked-groove effects on the early things have short delay times of a little less than 1 second. Probably 1/78 of a minute due to the 78 RPM speed.
On a somewhat related note, did anyone here ever get the issue of Mad Magazine with the record in it called "A Super Spectacular Day"? It had the grooves set up so it would play a different ending each time depending on which one the needle happened to fall into. I assume this means there was a continuous circular groove at one point that had multiple spiral grooves going inward off of it. Kind of cool effect.
