From Dirk the Daring:
Though I still think it sounds like a song, I sure don’t recognize anything specific. Googling suggests that “lyrical and edible” refers to “the sensory and creative pairing of cannabis edibles with music to enhance experiences, or to tangible, artistic food items”, which I’m pretty sure isn’t what this is about!
Comics I Don't Understand 
It reminded me of “Justified and Ancient” by the KLF but I don’t think it has anything to do with that.
They just sing hymns? (Holey music)
I know “lyrical, spherical, and diabolical”, there was a TikTok thing with the Kilted Donut Choir, and apparently you shouldn’t mix edibles and Lyrica, but I don’t see anything that makes actual sense.
