SPOILER WARNING: The following article contains spoilers for last week's episode of Riverdale Season 2, Nighthawks.

In "Nighthawks," last week's episode of the Archie Comics-based drama Riverdale, the CW series introduced the concept of an illicit new drug infecting the minds of the youth of the series' titular town: Jingle Jangle.

While we don't know a lot about the properties of the drug, it's referred to as an "upper" by Reggie, and in a key moment of the episode, was sold to Moose and Midge (who later experiment with the substance before certain...deadly circumstances courtesy of a hooded figure).

Well, where did the "Jingle Jangle" come from? It turns out, it's the name of an old track released on an Archies album in 1970 titled, yes, "Jingle Jangle." The track comes from a brief era when real, full Archies albums were actually produced (in the late-60s and early-70s) and were quite popular. "Jingle Jangle" itself even topped Canadian charts for one week in 1970!

Have a listen to "Jingle Jangle" by the bubblegum pop band The Archies below.

Airing at 8 p.m. ET/PT on the CW, Riverdale stars K.J. Apa as Archie Andrews, Lili Reinhart as Betty Cooper, Camila Mendes as Veronica Lodge, Cole Sprouse as Jughead Jones, Madelaine Petsch as Cheryl Blossom, Ashleigh Murray as Josie McCoy and Casey Cott as Kevin Keller.
