Not bad, but let me present you with the definitive cover: The Main Squeeze - that solo trounces everything, I’d go as far as, even the original.

I love that there’s a little guitar break right after that question, almost like a response

I see you updated your initial comment to replace Piano Man with The Entertainer (or at least, I don’t remember seeing the latter there before). I’m not sure I like it better than the Weird Al song, but it could give it a run for its money. (I wouldn’t answer Piano Man, which is a song I live, only because IMO it’s not “about the music industry” enough.)

Rounding out my list would be Sell Out by Reel Big Fish, The Load-Out/Stay by Jackson Browne (if it doesn’t have the same problem as Piano Man), and Life’s Been Good to Me So Far by Joe Walsh. That last one is not because I particularly like it, but because it’s the only one that came to mind without having to read other people’s answers.

If we tease that apart a bit, kabbalistically, we observe first and foremost that an onion has layers; that it is a food; and that the word onion sounds like “a nun”. From this we can derive that the piece of commentary referenced invokes a sense of layered meaning, is nourishing, and inspires religious devotion.

Digging, pun intended, a little deeper, we find that the etymological root (again intended) of the word is the Latin unio, unionis. Obviously “union” is right there –and this is not a coincidence because nothing is ever a coincidence, in Kabbalah– so we must understand that these layers of meaning are unified. Furthermore, the Latin word also is used to demote a large pearl, harkening to the “pearl of great price” allegorically mentioned by Christ as a stand in for spiritual wisdom; seeming to imply that not only is the above all unified but spiritually sound from the perspective of Christian soteriology.
