Maggie Rogers recently surprised a young fan on TikTok providing the harmonies to her own “New Song.”

The fan – named Emma Ogier (@immaoger) – was looking for a fellow TikTokker to add vocals to the cover, but little did she know that Rogers herself would jump onboard.

“hey emma 🙂 i’m not @delwatergap but i know his part,” Rogers wrote, referring to the song’s original backing vocalist, S. Holden Jaffe.

Not soon after, Jaffee also got in on the fun, stitching the video once more to add an extra layer of harmonies.

(As some Deadheads may recall, Rogers sat-in with Dead & Company for their 2019 Halloween gig at Madison Square Garden.)

Watch Ogier’s original TikTok and the ensuing collaborative clips below:
