They sing complaints about their city-state, here is one excerpt:
Stray cats get into noisy affairs
At night my neighbor makes weird animal sounds
People put on fake accents to sound posh
And queue up 3 hours for donuts
Will I ever live till eighty five to collect my CPF?
It sounds like a terrible place:
Old National Library was replaced by an ugly tunnel
Singaporean men can’t take independent women
People blow their nose into the swimming pool
And fall asleep on my shoulder in the train
Full lyrics and explanation are here. Yet it is now legally banned for foreigners to sing the complaints. Here is a video of the Choir, definitely recommended, best video I’ve seen this year and do watch it through to the end.
For the pointer I thank Chug Roberts.
