One thing to consider is a strategy used in Jewish singing contexts (which I see relatively rarely done in other contexts—but maybe it’s super common and I just don’t know the word to describe it!) Before singing the first verse or the chorus, you do a wordless verse where you’re just using nonsense syllables like “lai-dai-lai” or “yai-dah-dai-dai” that matches the song. This enables folks to pre-load the music before having to learn the words, and gives implicit social permission to, if you forget the words, to just do nonsense syllables that match the words. (A common problem if it’s a Hebrew text you’re unfamiliar with and you fall behind in reading it!)
(These are sometimes called niggunim, from the Hebrew for “tune” or “melody” for those wanting to google; for what should be fairly obvious reasons about a false cognate, I didn’t lead with that vocabulary term)
So for example, for The Circle, you’d start with something:
”Yah dai dai dai daiiii?
Dai dai, daaaai dah daaaai.
Yah dai dai dai daiiii?
Dai dai, daaaai dah daaaai.
Yah dai dai dai daiiii
Lah dah dai lai lai
Bah dah baiiih bah bah
Bah da bah baii bah
Bah da baiiii da baiii
Dai dai, daaaai dah daaaai.”
To presage the beat of verses like:
“So will we bring our families in,
Circle, grow and grow.
those whom Nature made our kin?
Circle, grow and grow.
Countless likenesses we find,
by our common blood bestowed.
What a debt of care is owed;
what a blesséd tie that binds!
Circle, circle, grow and grow.”
(The Circle is a little tricky in that the first verse starts slightly different, but trust me, this social technology extends to that use case as well, it’s not uncommon to have that in Jewish songs)
For anyone reading this: if you’re ever in a situation where you wore a suit when others are less formal, Do Not Panic.
Remove tie (if wearing tie) and place in inside jacket pocket. Remove jacket and place out of view. Unbutton top button of collar, if buttoned. Roll up sleeves. Sit in a way that pants aren’t visible, if possible.
Boom, you’re now down to something much less formal in under 30 seconds.
