I did a search for the phrase "first quad single" on the forum and got nothing. I find it hard to believe this hasn't been discussed before.
Anyway, I was browsing online through the May 1, 1971 issue of Billboard Magazine, and came across an article on page 45, partially quoted below:
"4 -CHANNEL DISK
The Bob Crewe group of labels (Crewe, Generation, Maxwell and others) has released the first matrix 4 -channel compatible single, according to Lawrence LeKashman, president of Electro -Voice, Buchanan, Mich. LeKashman views this as a step toward the 4 -channel jukebox, although he said he has not had time to sound out the four domestic jukebox manufacturers. The New York-based Crewe label released "Jesus Made Me Higher/Put Your Hand in the Hand" by Adam Rogers and the 11th Version. LeKashman, whose firm developed an encoder and decoder to deliver 4 -channel sound, explained that the single is compatible, thus suitable for the regular stereo or even monaural jukeboxes."
Here's a picture of the single, which mentions 4-channel playback on the label:

Obviously, this is an EV-encoded single. But does this qualify as the first quad single ever released?
